Question

A body travels a distance of 24m in 3×10-2s . Assuming it's speed was constant, find it's kinetic energy take 1.5×10-20kg as the mass of body

Answer 1

Since there is no information about any change in the direction of the object therefore we can also assume it to be velocity of the object here.

Velocity (v) = $\frac{24}{3.10^{-2}}$

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

                       = 1/2 . 20 . 8.10^2

                      = 8 x $10^{3}$ J
