In first question, as we know that, the potential energy is given by m g h.
00:10
In this formula, m is represent the mass of object.
00:17
G is an gravitational acceleration with value is 10 meter per second square.
00:25
And h is represent the height at which.
00:30
Object is place.
00:33
Now there are three positions of the ball, but the mass of the ball remain same.
00:43
The gravitational acceleration is also remained same.
00:46
So we can say that in this case, potential energy is proportional to the height.
00:54
So at the position a, the height is maximum as we can see from this figure.
01:05
So we can say that the potential energy of the ball is also maximum at the position a.
01:15
Now the kinetic energy can be given by 1 by 2 mv square...
