In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for the rockets position measured from the center of the Earth is given by y(t)=(R3/2+3g2Rt)2/3j where R is the radius of the Earth (6.38 106 m) and g is the constant acceleration of an object in free fall near the Earths surface (9.81 m/s2). a. Derive expressions for vy(t) and ay(t). b. Plot y(t), vy(t), and ay(t). (A spreadsheet program would be helpful.) c. When will the rocket be at y=4R? d. What are vy and ay when y=4R?
A turntable is off and is not spinning. A 0.2 g ant is on the disc and is 5 cm away from the center. The turntable is turned on and 0.6 s later it has an angular speed of 33 rpm. Assume the angular acceleration is constant and determine the following quantities for the ant 0.3 s after the turntable has been turned on. Express all quantities using appropriate mks units. @= V= Enter a number ih units. atan = arad = a = Fnet =
You have a horizontal grindstone (a disk) that is 88 kg, has a 0.31 m radius, is turning at 89 rpm (in the positive direction), and you press a steel axe against the edge with a force of 17 N in the radial direction. Assuming that the kinetic coefficient of friction between steel and stone is 0.20, calculate the angular acceleration of the grindstone in rad/s2. What is the number of turns, N, that the stone will make before coming to rest?
An ultracentrifuge accelerates uniformly from rest to 100,000 rpm in 2.0 min. If this ultracentrifuge accelerates 2.0 seconds starting from rest, what is the magnitude of the centripetal acceleration in unit of gravitational acceleration g for your sample sitting at 6.0 cm from the center axis? Use g = 9.8 m/s2. Hint: compute the centripetal acceleration in unit of m/s2 first, then divided by g will be your answer. For example, if your centripetal acceleration is 19.6 m/s2, your answer measured in unit of g is 2.0.
A 1.5 kg block and a 2.5 kg block are attached to opposite ends of a light rope. The rope hangs over a solid, frictionless pulley that is 33 cm in diameter and has a mass of 0.75 kg. The pulley can be modeled as a cylinder. When the blocks are released, what is the acceleration of the lighter block? Express your answer in meters per second squared.
A light, rigid rod is 75.5 cm long. Its top end is pivoted on a frictionless horizontal axle. The rod hangs straight down at rest with a small, massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. Wwhat minimum speed at the bottom is required to make the ball go over the top of the circle? m/s
The rotation of the earth causes a centrifugal effect on a mass near the surface of the earth. This slightly changes the effective acceleration due to gravity. We can call the old acceleration due to gravity go and the effective acceleration geff. a. Show that the angle between go and geff can be expressed as /55'R sin(e) cos(0)) = tan Go - Ns/s, R sin²(0) where 0 is the angle between the angular velocity of earth and the position of the mass near the surface of the earth. b. How small that o if 0 is 45° and R is the radius of the earth. m Tm/S
