Question

An object of mass 20 kg is drop from height of 4 metre. Fill in the blanks in the following table by computing the potential energy and the kinetic energy in each case.​

Answer 1

Heya!!!

First  We need to find the potential energy

we know, Pe=mgh

Where g is the gravity

Given

M=20kg

H=4m

G=10m/s

Pe=20X10X4

Pe= 800J

Let V Be 0

Ke= 1/2 mv2

Ke= 1/2X20X0X0

Ke=10X0X0

Ke=0 J

Hope its right!!!
