Concept explainers
A solid cylinder and a hollow cylinder have the same mass, same radius, and turn on frictionless, horizontal axles. (The hollow cylinder has lightweight spokes connecting it to the axle.) A rope is wrapped around each cylinder and tied to a block. The blocks have the same mass and are held the same height above the ground as shown in Figure Q10.20. Both blocks are released simultaneously. The ropes do not slip. Which block hits the ground first? Or is it a tie? Explain.

- A block is placed on top of a vertical spring, and the spring compresses. Figure P8.24 depicts a moment in time when the spring is compressed by an amount h. a. To calculate the change in the gravitational and elastic potential energies, what must be included in the system? b. Find an expression for the change in the systems potential energy in terms of the parameters shown in Figure P8.24. c. If m = 0.865 kg and k = 125 N/m, find the change in the systems potential energy when the blocks displacement is h = 0.0650 m, relative to its initial position.

- A small 0.65-kg box is launched from rest by a horizontal spring as shown in Figure P9.50. The block slides on a track down a hill and comes to rest at a distance d from the base of the hill. Kinetic friction between the box and the track is negligible on the hill, but the coefficient of kinetic friction between the box and the horizontal parts of track is 0.35. The spring has a spring constant of 34.5 N/m, and is compressed 30.0 cm with the box attached. The block remains on the track at all times. a. What would you include in the system? Explain your choice. b. Calculate d.arrow_forwardIn a basketball game, lebron made a dunk. At the time he was hanging on to the rim, the rim was displaced 15cm and he was 1.5m above the floor.

- Ashley is working on a problem in which a 13 kg rock rolls down a 12 m hill. She reasons that since the rock is moving downward, that the work performed by gravity must be negative, so the total work done is; (9.8m/s^2) (11kg) (-12m) = - 1300 J Is ashley's reasoning correct? if so, explain. If not, what mistake did she make?arrow_forwardConsider the mechanical energy of a body at rest on the ground at the Earth's equator, at re= 6400 km Consider the mechanical energy of the same body at rest on the ground at the South pole, at re = 6400 km. For this problem, we consider the Earth to be spherical. (Remember, the object at the equator traces a circular path, the object at the Pole does not.) G = 6.67 × 10−11 Nm2 kg−2, and the mass of the Earth is M = 5.97 × 1024 kg. How much more mechanical energy per kilogram does an object on the ground at the Equator than on the ground at the Pole?
