Question

which is having a higher value of momentum A bullet of mass 10 g moving with a velocity of 400 m/s or a cricket ball of mass 400 g thrown with the speed of 25
km/h?

Answer 1

Answer:

which is having a higher value of momentum A bullet of mass 10 g moving with a velocity of 400m/s or a cricket ball of mass 400g thrown with the speed of 90km/h? Therefore the cricket ball having the mass of 400 g and the speed of 90km/hr is having the higher value of momentum.

Answer 2

Answer:

Explanation:

We know,

Momentum= mass* velocity

In first case,

Mass of bullet=10 g= 0.01 kg

Velocity of bullet= 400 m/s

Hence, momentum= 400*0.01 = 4 kg m/s

In second case,

Mass of cricket ball=400 g= 0.4 kg

Velocity of cricket ball = 25 km/h = 25*5/18 m/s = 125/18 m/s

Hence, momentum= 0.4* 125 / 18=25/9 =2.8 kg m/s

Since 4>2.8,

Momentum of a bullet> momentum of cricket ball.
