Question

calculate the momentum of a ball of 500 gram moving with a velocity of 72 metre per hour
answer is 10 kg m/s​

Answer 1

$\mathfrak{\huge{Answer:-}}$

______________________

There is a slight error in your q

It is supposed to be

72 km/h

____________________

$\tt{\underline{Known\:Terms}}$

p = momentum

m = Mass

v = Velocity

_______________________

$\tt{\underline{Formula}}$

$\red{\fbox{p=mv}}$

_______________________

$\tt{\underline{Answer:-}}$

Rememeber that the quantities must be in it's units

m = 500 g = 0.5 kg

v = 72 km/h = $\frac{72\times 1000}{3600}$ = 20 m/s

Applying the formula we get,

p = 0.5×20

p = 10 kg m/s
