Answer:
Formula = mgh
Therefore m= mass
g (gravity)= 9.8 m/s²
h = 30m
Therefore,
0.2×9.8×30= 58.8

Answer:
Answer:In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
