Question

A ball of mass 100g is tgrown vertically at a speed of 10m/s. find its kinetic energy.​

Answer 1

ANSWER

Given,

m= 100g = 0.1kg

v = 10m/s

Kinetic energy of ball is given by

KE =

$\frac{1}{2} m {v}^{2}$

$= \frac{1}{2} \times 0.1 \times 100$

= 5 Joules

THANKS

Answer 2

m = 100 g = 0.1 kg

v = 10 m/s

$\frac{1}{2} mv {}^{2} \\ \\ \frac{1}{2} \times 0.1 \times 10 \\ \\ \frac{1}{2} = 0.5 \: joule$
