Question

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

Answer 1

We know that
K. E. = 1/2 mv²
= 1/2 x 15 x (4)2
= 8 x 15 = 120

Answer 2

Hello,

Mass of the object is 15 kg
Uniform velocity = 4m/sec

Kinetic energy =
$\frac{1}{2} m {v}^{2} = \frac{1}{2} \times 15 \times 16 = 120 \: joules$
Hope this will be helping you ✌️
