Answer:
t = 5.19 s
Explanation:
We have,
Height of the cliff is 132 m
It is required to find the time taken by the ball to fall to the ground. Let t is the time taken. So, using equation of kinematics as :

So, it will take 5.19 seconds to fall to the ground.

Answer:
= 33.33 cm
Explanation:
Given:
When mass,
=21 kg
distance travelled is
= 140 cm
When mass,
=5 kg
distance travelled is
= ?
Hooke's law state that within elastic limit, when an external force is applied to a body, the body gets deformed and when the force is released the gets back to its original form.
Therefore according to the question,


= 33.33 cm
Distance travelled is 33.33 cm when mass is 5 kg.
