Answer:
Explanation:
The formula S=(at^2)/2 will be used during the entire explanation.
1. 4 = (2t^2)/2
t = 2 s.
V = at = 2 * 2 = 4 m/s
2. 8 = (2t^2)/2
t = 2.8 s
iii. 2s
iv. 2.8 - 2 = 0.8s

The answer is potential energy
Explanation:
The potential energy is the energy possessed by a body by virtue of it position
For example the water at the top of the dam is being held at a height h above the bottom of the dam
Then the potential energy
PE= weight of the water* the height
PE= m*g*h
