A ball is thrown straight up from a point 2 m above the ground. The ball reaches a height of 3 m above its starting point and then falls 5 m to the ground. When the ball hits the ground what is its displacement from its starting point? (A) 0 m (B) 8 m below (C) 5 m below (D) 2 m below (E) 3 m above 13. Two balls of mass M and 2M are thrown horizontally with the same initial velocity v0 from top of a tall tower and experience a drag force of –kv(k > 0) where v is the instantaneous velocity. In order to solve this you need to find out how long the ball was in the air and then use that time to find how far away it lands. If we look at just the Y direction (vertical), then we have a displacement of -50m (since we start at the roof and go down), an initial velocity of 0, and an acceleration of -9.8 m/s2.
