Question

Acricket ball pf mass 150g moving with a velocity 15m/s bring to the rest by player in 0.05s calculate impulse and average force

Answer 1

Impulse = Change in momentum
= m (v - u)
= 150 × 10^-3 kg × (0 m/s - 15 m/s)
= -2.25 kg m/s

Average Force = Impulse × Time
= -2.25 kg m/s × 0.05 s
= -0.1125 N

[Negative sign in both indicates that both vectors are in opposite direction of motion of ball]
