A2 kilogram object falls a distance of 5 meters. how much potential energy does this object have before it falls? how much work is done on it by gravity as it falls

1) Potential energy before the fall: 98 J

The gravitational potential energy of an object is given by:

where m is the mass of the object, g is the gravitational acceleration and h the heigth of the object above the ground.

In this problem, m = 2 kg, g = 9.8 m/s^2 and h = 5 m: substituting into the equation, we find

2) Work done by gravity: 98 J

The work done by a force is given by:

where

F is the magnitude of the force

d is the displacement of the object

is the angle between the direction of the force and the displacement

In this problem:

d = 5 m

Therefore,

momentum of soft ball three times less than baskey ball
