Question

Given that the kinetic energy of an object is 100J.If the mass of object is 2kg then find it's speed.​

Answer 1

Answer:

KE = 1/2 MV^2

100 = 1/2 ×2 ×v^2

v= 10m/s

The mass of the object, m = 2 kg

The speed of the object, v = ?

The Kinetic Energy, K.E = 100J

We know that ,

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

From this ,,,

Kinetic Energy ,K.E = 1/2 × 2 × (v)^2

100 = v^2

v = 10 m/s

The Velocity is 10 m/s
