Question

An object of mass 15 kg is moving with a uniform velocity of 4 ms-¹ . calculate the kinetic energy possessed by the object

Answer 1

Given-

Mass of object = 15 kg

Velocity of object = 4$ms^{-1}$

To find-

Kinetic Energy of object

Solution-

Kinetic Energy = $\frac{1}{2}mv^2$

where

• m= mass
• v = velocity

putting Values-

$\red\implies$ $\frac{1}{2}×15×(15)^2$

$\red\implies$ $\frac{1}{2}×15×225$

$\red\implies$ $\sf\green{1687.5}$
