Question

10. Derive a mathematical expression for kinetic energy of an object of mass 'm'
initially at rest then finally moving at velocity 'V'. If a boy of mass 60 kg is
moving with a velocity of 3 m/s, calculate kinetic energy possessed by his
body.
​

Answer 1

Answer:

$k = \frac{1}{2} \times m \times {v}^{2}$

Explanation:

mass = 60kg

velocity = 3m/s

$k = \frac{1}{2} \times 60 \times 3 \times 3$

$k = 30 \times 3 \times 3$

$k = 270 \: joules$
