Question

A bullet of mass 10 g moving with a velocity of 400m/s or a cricket ball mass 400 g thrown with speed of 90km/h which one have a higherbvalue of momentum

Answer 1

momentum = mass * velocity

For bullet, momentum = 100*400 = 40000 g*m/s
For ball, momentum = 400*90*5/18 = 10000 g*m/s

So, bullet has more momentum

Answer 2

v=400m/s = 1440kmph
mass = 10g
mass of ball =400 g
v= 90kmph =25 m/s
now p=mv
p bullet = 1/100kg * 400 = 4 kg•m/s
p ball = 4/10 * 25 = 10 kg•m/s
