5. All the ramps below are 5 meters high. We know that the KE of the block at the bottom of each ramp will be equal to the loss of PE (conservation of energy). Find the speed of the block at ground level in each case. [Hint: Do you recall from earlier chapters how much time it takes something to fall a vertical distance of 5 m from a position of rest (assume = g 10 m/s²)? And how much speed a falling object acquires in this time?] This gives you the answer to Case 1. Discuss with your classmates how energy conservation provides the answers to Cases 2 and 3. 5m Case 1 Speed: = m/s Case 2 Speed = m/s Case 3 Speed m/s
4. A roller coaster car with its three passengers (a total of 450. kg) is pulled up to the top of a 30.0 meter hill where it is released at a speed of 1.00 meter per second to begin its hurtle down the track toward a 15.0 meter diameter loop the loop at the bottom. Unfortunately the maintenance crew still has some work to do on the old rusty roller coaster track and the average frictional force on the 65.0 meter long angled descent is 595 N. Luckily the loop the loop portion of the roller coaster track has been recently polished and Teflon coated to reduce friction to practically nothing. What will be the speed of the car at the top of the loop the loop, and will this be enough to have the car stay on the track all the way round the loop?
