Use conservation law methods to solve all problems. A crate, initially traveling horizontally with a speed of 18 ft/s, is made to slide down a 14 ft chute inclined at 35°. The surface of the chute has a coefficient of kinetic friction uk, and at its lower end, it smoothly lets the crate onto a horizontal trajectory. The horizontal surface at the end of the chute has a coefficient of kinetic friction uk2. Model the crate as a particle, and assume that gravity and the contact forces between the crate and the sliding surface are the only relevant forces. Using conservation law methods, if uk = 0.35, what is the speed with which the crate reaches the bottom of the chute (immediately before the crate's trajectory becomes horizontal).

The two ramps pictured here each have a region of length L with kinetic friction coefficient uk and are otherwise frictionless. Identical masses m start at identical heights up the ramps, with the same initial velocity down the ramp. How do their final speeds compare when they reach the far right-hand side? (The answer requested here is qualitative and does not require detailed calculation). L m m Vi #0 Vi O Mass is moving faster in #1 The masses are moving at the same speed. Mass is moving faster in #2 O There is not enough information to decide. L Mk#0 1 2 m m Vf,1 V₁,2
A wooden block starting from rest, slides 6 m down a 45° slope, then 3 m, along a level surface then up a 30° inclined until it comes to rest again. The coefficient of friction is 0.15 for all surfaces of contact. Find (a) distance S, (b) total distance travelled until it stops at D (c) velocity of block as it moves backward from D and horizontal distance of 2 m from C. *Hint: Do not worry about finding the weight of the block. Then, look closely at the figure, notice the forces that you need to solve first in order to solve the problem. 45 30 W óm Fi 45 B 130 F2 -3m-
A bar tender slides a beverage across a slick table (assume frictionless) at a velocity of 5 ft/s. The drink was prepared with 1” remaining between the top of the glass and the top of the liquid. Assuming a 3”-diameter cylindrical glass (feel free to model as a 3” × 3” square crosssection if that helps), how slowly must the drink be brought to rest to avoid anything spilling out the top of the glass?
A box on a rough floor is pulled with a force of 1000N along a rope that creates an angel 25° above the horizon. The coefficient of friction is 0.40. If the box accelerates at a rate of 5m/s^2, what is the mass of the box?
What is the safe maximum speed without tipping or skidding for a 13,200 N automobile running around a flat curve of 80 m radius? Its center of gravity is 0.60 m above the road surface and the wheel tread is 1.5 m, and f = 0.50.
Some sliding rocks approach the base of a hill with a speed of 12 m/s. The hill rises at 36° above the horizontal and has coefficients of kinetic friction and static friction of 0.45 and 0.65, respectively, with these rocks. (a) Find the acceleration of the rocks as they slide up the hill. (b) Once a rock reaches its highest point, will it stay there or slide down the hill? If it stays, show why. If it slides, find its acceleration on the way down.
A carton is given a push across a horizontal surface. The carton has a mass m, the push gives it an initial speed of 2.30 m/s, and the coefficient of kinetic friction between the carton and the surface is 0.145. (a) Use energy considerations to find the distance (in m) the carton moves before it stops. (b) What If? Determine the stopping distance (in m) for the carton if its initial speed is doubled to 4.60 m/s. m
You are called as an expert witness in a trial for a traffic violation. The facts are these: A driver slammed on his brakes and came to a stop with constant acceleration. Measurements of his tires and the skid marks on the pavement indicate that he locked his car’s wheels, the car traveled 192 ft before stopping, and the coefficient of kinetic friction between the road and his tires was 0.750. He was charged with speeding in a 45 mi>h zone but pleads innocent. What is your conclusion: guilty or innocent? How fast was he going when he hit his brakes?
A box is sliding with a constant speed of 4.00 m>s inthe +x-direction on a horizontal, frictionless surface. At x = 0 thebox encounters a rough patch of the surface, and then the surface becomeseven rougher. Between x = 0 and x = 2.00 m, the coefficientof kinetic friction between the box and the surface is 0.200; betweenx = 2.00 m and x = 4.00 m, it is 0.400. How much time does it take the box to come to rest after it first encounters the rough patch at x = 0?

Review ConstantS In the vertical jump, an athlete starts from a crouch and jumps upward to reach as high as possible. Even the best athletes spend little more than 1.00 s in the air (their "hang time"). Treat the athlete as a particle and let ymax be his maximum height above the floor. Part A To explain why he seems to hang in the air, calculate the ratio of the time he is above ymax/2 (moving up from ymax /2 to ymax and then moving down to ymax/2) to the time it takes him to go from the floor to that height. Ignore air resistance. ΑΣφ. ?
A cord passing over a pulley connects two masses, as shown, where m, = 3.00 kg and m, = 6.00 kg. The system accelerates with a magnitude of 1.31 m/s?. The coefficient of kinetic friction between the masses and the incline is the same for both masses. Assume the pulley is frictionless, and the cord is massless.

Draw free-body diagrams for both blocks and write Newton's second-law equations in the x- and y-directions. Condense your four equations into two by substituting, and solve the system of two equations for the two unknowns, u and T. (b) What is the tension (in N) in the cord?
