Answer:
The gravitational potential energy (PE) of a particle or a system of particles is a form of energy that exists due to its position. Mathematically, it is expressed as the product of mass, gravitational acceleration, and the vertical displacement.
Explanation:
Given data:
Mass of the storage box,
Height,
The gravitational potential energy of the storage box can be expressed as,
Answer:
final velocity will be equal to 8.28 m/sec
Explanation:
Let the mass is m
Height fro which it is fallen h = 3.5 m
Acceleration due to gravity
We have to find the final velocity of the mass
As the mass is dropped from rest so initial velocity is 0 m/sec
Using energy conservation
So
So final velocity will be equal to 8.28 m/sec
