Question

Find the kinetic energy of a stone 10 kg moving with a velocity of 10 m/s

Answer 1

$\huge\mathcal{Answer:}$

we know that "kinetic energy" equals to

$\frac{1}{2} {(mass)} \times (velocity)^{2}$

i.e. $=\frac{1}{2}{mv}^{2}$

___________________

To Find :- kinetic energy of the stone.

solution :-

Given mass = 10kg

Velocity = 10m/s

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

$= \frac{1}{2} \times 10 \times 10$

$= \frac{1}{2} \times 20$

$= 10 Joule$

Answer 2

Answer:

M=10kg

V=10m/s

kinetic energy=1/2×M×V^2=1/2×10×10×10=500J
