Question

A ball of mass 2kg is allowed to free fall on smooth horizontal surface from height h is equals to 10

Answer 1

Answer:

it's acceleration is maximum..........

Explanation:

Hope it is correct........

Answer 2

The potential energy of the ball is 200 joules.

Explanation:

Given that,

Mass of the ball, m = 2 kg

Height from which the ball is thrown, h = 10 m

Let us assume to find the potential energy of the ball. It is given by the relation as :

$P=mgh$

$P=2\ kg\times 10\ m/s^2\times 10\ m$

P = 200 Joules

So, the potential energy of the ball is 200 joules. Hence, this is the required solution.
