Question

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 25
km/h?

Answer 1

Answer:

A bullet of mass 10g moving at a velocity of 400 m/s has a higher velocity than a cricket ball of mass 400g with a velocity of 25km/h.

Explanation:

Given:

m1 = 10g = 0.01kg

v1 = 400 m/s

m2 = 400g = 0.4 kg

v2 = 25km/h = 6.944 m/s (CONVERTING km/h to m/s to match the units)

P1 = m1 x v1

P1 = 0.01 x 400

P1 = 4 kgm/s

P2 = m2 x v2

P2 = 0.4 x 6.944

P2 = 2.7776 kgm/s

Since P1 > P2,

Bullet of mass 10g moving at a velocity of 400 m/s has a higher velocity than a cricket ball of mass 400g with a velocity of 25km/h
