Question

A 10 kg ball is dropped from a height of 10m find a)the initial potential energy

Answer 1

Answer:

increase with respect to the time and mass

Answer 2

Given data:-

Here,

—› Mass = m = 10 kg

—› Heigth = h = 10 m

—› We know, acceleration due to gravity = g ( constant ) = 9.8 m/s²

Solution:-

We use formula to find

Gravitational intitial potential energy of ball at height 10 m with mass 10 kg.

—› Initial potential energy = mgh

—› Initial potential energy = 10 × 9.8 × 10

—› Initial potential energy = 98 × 10

—› Initial potential energy = 980 Joule.

Hence,intitial potential energy of ball at height 10m with mass 10kg is 980 joule.
