Question

which has a greater Momentum A bullet of mass 10 gram moving with a velocity of 400 m per second a cricket ball of mass 412 thrown with a velocity of 90 km per hour

Answer 1

momentum of bullet= mv
10/1000*400
4kgm/s
momentum of ball=mv
412*25
1300kgm/s
ball have more momentum
b.

Answer 2

!!!

given :-

mass of bullet = 10g = 0.01kg

velocity of bullet = 400m/s

therefore it's momentum = mv

= 0.01 * 400

= 4kgm/s

mass of cricket ball = 412g = 0.412kg

velocity of the cricket ball = 90km/h = 90 * 5/18 = 5 * 5 = 25m/s

momentum of the cricket ball = mv

= 0.412 * 25

= 10.3kgm/s

hence, the momentum of cricket ball is greater than of the bullet.
