Question

An object of mass $15kg$ 15 kg is moving with a uniform velocity of $4m{s}^{-1}$. What is the kinetic energy possessed by the object?

Answer 1

Step 1: Given Data

Mass (m) $=15kg$

Velocity (v) $=4m{s}^{-1}$

Step 2: Formula used

$Kineticenergy(K.E)=\frac{1}{2}m{v}^2$

Step 3: Calculating kinetic energy

$$\begin{gathered} K.E=\frac{1}{2}x15x4x4 \\ K.E=120J \end{gathered}$$

Hence, the kinetic energy possessed by the object is $120J.$
