which is having a higher value of momentum - a bullet of mass 10gmoving with a velocity of 400m/s or a cricket ball of 400g thrown with the speed of 90km/hr?

First, we know that

Momentum = Mass × velocity OR

p = mv

Now,convert g into kg

10g = 0.01 kg
400g = 0.4 kg

In first case p = (0.01)(400)
Momentum = 4 kg m/s

In seconf case, convert km/hr into m/s

= 90* 5/18 m/s or 25 m/s

Momentum = (0.4)(25)
p = 10 kg m/s

On comparing we can clearly see that
4 kg m/s < 10 kg m/s

Hence, cricket ball of 400g thrown with speed of 25 m/s will have more momentum.

Hope it helps
