1. Acceleration Due to Gravity

2. the acceleration due to gravity (9.81 m/s 2 [↓]) always acts down -when the object is travelling towards the earth -when the object is travelling away from the earth -when the object is stopped

3. 1.A boy jumps from a bridge. Determine his velocity after he falls for 3.0 s.

4. 2.A stone is thrown from a bridge with an initial velocity of 20.0 m/s. Determine the velocity after 2.2 s if the direction of the initial velocity is: (a) upward (b) downward

5. c)If the stone is thrown up, at what time will it reach its maximum height?
