Match the facts to the examples. the force of gravity increases with an increase in the mass of objects. acceleration due to gravity is independent of the mass of objects. air resistance increases with an increase in the surface area of objects. two falling inflated balls of different masses land at the same time. arrowright a large, massive dog weighs more than a small dog. arrowright a crumpled ball of paper falls faster than a sheet of paper of the same mass. arrowright

A23 kg log of wood begins from rest, 300 m up a sluice (a water track used to transport logs, think of it as an inclined plane with negligible friction) inclined at 20° to the horizontal. after it reaches the flat waterway at the bottom it collides elastically with a 100 kg block of wood initially at rest near the base of the incline. (a) how long does it take the 23 kg log to travel down the incline? (b) what is the speed of the 23 kg log at the bottom of the incline? (c) what are the velocities of both blocks of wood after the collision? (d) what is the total kinetic energy before the collision? (e) what is the kinetic energy of the 23 kg log after the collision? (f) what is the kinetic energy of the 100 kg block of wood after the collision? (g) what is the total kinetic energy after the collision? (h) compare the total initial and total final kinetic energies. is this consistent with what you would expect for elastic collisions? explain!
