Question

A body of mass 4 kg is moving with velocity 5 m/s. Calculate kinetic energy possessed
by the body.​

Answer 1

Answer:

m=4kg, v=5m/s,k=?

we know. that -

k=1/2mv^2

so, 1/2*4*5*5

=50joules.

Explanation:

kinetic energy of a body is equals to the half of the product of mass of the body and the square of its velocity.

Answer 2

We have to find kinetic energy of the body

Kinetic energy is equal to half the product of mass and the square of velocity.

The formula for kinetic energy(K) is K=1/2*M*V^2  where M stands for mass and V stands for velocity.

GIVEN

Mass (M)=4 kg

Velocity (V)=5 m/s

Solving for kinetic energy we get 1/2*4*5^2= 50 Joules

The kinetic energy of the body is equal to 50 joules.
