A 2.0 g bullet initially moving with a speed of 87 m/s passes through a block of wood. 0n exiting the block of wood, the bullet's velocity is 12 m/s, (the change in height is negligible). a. How much WORK did the force of friction do on the bullet as it passes through the block? b. If the block was 4.0 cm thick, what was the average force that the wood exerted on the bullet? 6. You are designing a free-fall rollercoaster and want to do the following: The 750 kg car should be moving at 15 m/s at the top of the first loop which will be 56.0 m above the ground. At what height should the ride start at in order to achieve this speed at the first loop? h n h R
