A man of mass 20 kg is running in a straight line with velocity 10 m/s. What is value of his kinetic energy?

হানি নাটস

The kinetic energy of the particle is given as-

K.E.=12mv2K.E. = \dfrac{1}{2}mv^2

mm: mass of the object

vv: speed of the object

K.E.=12×20×102J\Rightarrow K.E. = \dfrac{1}{2} \times 20 \times 10^2J

K.E.=1000J\Rightarrow K.E. = 1000 J
