- I need help with finding the magnitude and direction of the graph attached. For part a I've tried 2 times with this question using F = sqrt ((Fx2 + Fy2)) to find the magnitude and the direction using tan-1(y/x), and so far it still says incorrect. A. Calculate the magnitude and direction. B. When a fourth force is applied to the mass, it is observed that the velocity of the mass stops changing and remains constant. What are the horizontal and vertical components of that fourth force? (This all the information that I was given)arrow_forwardThe 47-kg boy is sliding down the smooth spiral slide such that his z coordinate decreases 2 m per turn of the spiral and his speed is 2 m/s. Neglect the size of the boy. (Figure 1) Figure Z r = 1.5 m Part A transcript Determine the r, 0, z components of force the slide exerts on him at this instant.

The mass of the sled + child is 35 kg, and the coefficient of kinetic friction is 0.060. d) Determine the speed of the sled + child at the bottom of the incline. e) How far along the horizontal stretch does the sled + child travel before stopping? f) What is the total time for the ride? g) Determine how much energy that is transferred to thermal energy. h) Determine how much work is done on the sled + child by the gravitational force while the child + sled is moving along the incline. i) By considering the energy of the system and energy transformations, determine the speed of the sled + child at the bottom of the incline.

- A 65 kg person running at 2.0 m/s jumps onto the skim board at right. The skim board is 50 cm wide and 120 cm long, with an area of 0.60 m². Part A Draw a sketch of this situation. Part B If the person jumps onto the board on sand with a coefficient of friction of f=0.50, what force will resist the forward movement of the board [N]? Recall the friction force is the normal force times the coefficient of friction. Part C Now assume the person jumps onto the board on a 0.50 cm film of fresh water at 30°C. Use Newton's law of viscosity to estimate the force resisting the forward movement of the board.arrow_forwardYou're driving home from the grocery store at 12 m/s with a 7.0 kg bag of groceries on the front seat when the light ahead turns red. Part A What is the shortest distance in which you can stop, after the brakes are applied, without the groceries sliding off the seat? The static and kinetic coefficients of friction are, respectively, 0.65 and 0.45. Assume that the surface of the seat is horizontal.

- If you put a uniform block at the edge of a table, as shown at left part of (Figure 1), the center of the block must be over the table for the block not to fall off. Part A If you stack two identical blocks at the table edge, as shown at the right part (Figure 1), the center of the top block must be over the bottom block, and the center of gravity of the two blocks together must be over the table. What is the maximum overhang possible? Express your answer in terms of the length L of each block. Hνα ΑΣφ S2 = Part B Figure What is the maximum overhang possible for three identical block?

A flatbed truck drives past you on a horizontal, flat road at 100 km/hr. Just when it passes you, a crate falls off the truck and lands flat on the ground and travels 50 m before coming to a stop. Find the coefficient of kinetic friction between the road and the crate. Assume that the initial speed of the crate is the same as the truck, 100 km/hr. In your solution, include appropriate free body diagrams (FBD) for the crate, and break up the forces acting on the crate into components either on the FBD or in a table of the components.arrow_forwardThree blocks move on a frictionless surface with a 56 N force acting on the 12 kg block as shown. Determine (a) the acceleration of the total system, (b) the tension in the cord connecting the 12 kg and the 3 kg blocks, and (c) the normal force exerted by the 3 kg block on the 1 kg block. I am especially confused by part c) I would really appreciate it if you could explain clearly. I originally thought (3kg)(acceleration), but would it be (1kg) (acceleration) for the Normal force exerted by the 3kg block on the 1 kg block instead?arrow_forward
- A 1660 kg rocket is to be launched with an initial upward speed of 59.0 m/s. In order to assist its engines, the engineers will start it from rest on a ramp that rises 53° above the horizontal (Figure 1). At the bottom, the ramp turns upward and launches the rocket vertically. The engines provide a constant forward thrust of 2000 N, and friction with the ramp surface is a constant 500 N.
