Question

The linear momentum of a ball of mass 50 g is
0.5 kg m s-1. Find its velocity.
​

Answer 1

Given,

Mass of the ball = 50 g = 0.05 kg

Momentum = 0.5 kg m/s

$\boxed{\bold{Momentum = mass \times velocity}}$

$\boxed{\bold{Velocity = \frac{Momentum}{mass}}}$

             

⇒ Velocity = 0.5/0.05

⇒ Velocity = 10 m/s

$\boxed{\bold{\therefore\:Velocity \:of \:the \:ball = 10 \:m/s}}$

Answer 2

Answer:

10m/s

Explanation:

p=mv ;

where; linear momentum=p ,mass=m, velocity=v.

p=0.5kg m/s, m=50g=0.05kg

v=p/m= 0.5/0.05 =10m/s
