Can anyone help me solve this question?
7. A student throws a water balloon vertically downwards from the top of a building. The balloon leaves the thrower’s hand at a speed of 6.0 m/s. air resistance may be ignored, so the water balloon is in free fall after it leaves the thrower’s hand. (a) what is its speed after falling for 2.0 s (b) how far does it fall in 2.0 s? (c) what is the magnitude of its velocity after falling 10.0 m?
