Solve for the following 1. A ball rolls down a ramp for 15 seconds. If the initial velocity of the ball was 0.8 m/sec and the final velocity was 7 m/sec, what was the acceleration of the ball in ft/s? (25 points) 2. A car travelling on want to merge into highway traffic via 100 meter long ramp. If the initial velocity is 15 m/s and it accelerates at 4 m/s?. How long does it take for the car to join the traffic?
