1. A student is playing pool. He hits the cue ball (white ball) towards the pyramid of other balls to start the game.
The cue ball travels 2.0 m [N], hits the formation of other balls and rebounds a distance of 0.80 m [N 30W] before stopping.
Determine the average velocity of the ball if the entire shot takes 1.2s.
2. A car is merging onto the highway via an on ramp with an initial velocity of 52 km/hr. The car accelerates at a rate of 2.0 m/s2for 7.2s before leaving the ramp and entering the highway.
- What is the length of the on ramp?
- What is the velocity of the car when it enters the highway?
