Question

A body of mass 60kg moves with uniform velocity of 5m/s . Find the kinetic energy possessed by the body. ​

Answer 1

Explanation:

We know that kinetic energy =

2

mv

2

So kinetic energy of given object = 120

Answer 2

$\large\underline{\sf{Solution-}}$

Mass of body (m) = 60kg

Velocity of the object (v) = 5 m/s

Kinetic energy (KE) =

$\sf{ \frac{1}{2} \times m \times {v}^{2} }$

$\sf{= \frac{1}{2} \times 60 \times {5}^{2} }$

$\sf{ = 1 \times 30 \times 25}$

$\sf{=750J}$

Hence, The Kinetic energy possessed by the body is 750J.
