Question

calculate the momentum of a cricket ball off mass of 0.15 kg travelling at a velocity off 144 km/h
​

Answer 1

Answer:

first change 144 km/h to m/s by multiplying by 5/18.

144*5/18 = 40 m/s

momentum (p) = mass *velocity

therefore, 0.15*40 = 6 (ANS)

Answer 2

m=0.15kg

v=144km/h=144×5/18=40m/s

momentum =mass×velocity

therefore, p=m×v

p=0.15×40

=6kgm/s
