Question

The kinetic energy of an object of mass m and moving with velocity of 5m/s

Answer 1

Given :

m= m

velocity = 5m/s

using the formula ke= 1/2mv^2;

ke= 1/2 ×m×(5)^2

ke = 1/2m×25

ke = 12.5m Joules

The mass of the object, m = m kg

The speed of the object, v = 5m/s

The Kinetic Energy, K.E = ?

We know that ,

$kinetic \: energy = \frac{1}{2} mv ^{2}$

From this ,,,

Kinetic Energy ,K.E = 1/2 × m × (5)^2

K.E = 1/2 × m × 25

K.E = 12.5 m J

The Kinetic Energy is 12.5 m J.
