Chapter 2, Problem 7MCQ
A ball is dropped from the top of a tall building. At the same instant, a second ball is thrown upward from the ground level. When the two balls pass one another, one on the way up, the other on the way down, compare the magnitudes of their acceleration:
- The acceleration of the dropped ball is greater.
- The acceleration of the ball thrown upward is greater.
- The acceleration of both balls is the same.
- The acceleration changes during the motion, so you cannot predict the exact value when the two balls pass each other.
- The accelerations are in opposite directions.

Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/s^2 until it reaches a speed of 60ft/s. Afterwards it maintains the speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 80 ft/s. Determine the distance traveled by Car A when they pass each other.Write the solution using pen and draw the graph if needed.
