An elevator is moving upward with a velocity of 15 m/s. Three seconds later, the elevator is still moving upward, but its velocity has been reduced to 6.0 m/s. What is the average acceleration of the elevator during the 3.0 s interval? After 3.0 s, If it maintains the same acceleration, what is the displacement of the elevator after 5 second time interval ? What will be the velocity after the 5 second ? Hint: Keep in mind that the...

Problem 1. You hit a bowling ball with a mallet, starting from rest. Every time you hit it, its velocity increases by exactly 10 cm/s. You start timing (t 0 seconds) at the instant you hit the ball the first time, and you hit it once every second. Two simplifying approximations: (1) Suppose each hit is very short, so the speed changes in a short amount of time and (2) suppose the ball doesn't slow down between hits a. Att...
