A cricket ball of mass 150 g moving with a velocity of 12 m/s is turne

1.	A cricket ball of mass 150 g moving with a velocity of 12 m/s is turned back with a velocity of 20 m/s on hitting the bat. The force of the ball lasts for 0.01 s. Find the average force exerted on the ball by the bat.
Answer» m = 0.150 kg, v = 20 m/s, u = -12 m/s and t = 0.01 s To find: Average force (F) Formula: F = \(\frac{m(v-u)}{t}\) Calculation: From formula, F = \(\frac{0.150[20-(-12)]}{0.01}\) = 480 N The average force exerted on the ball by the bat is 480 N.

Answer»

m = 0.150 kg, v = 20 m/s,

u = -12 m/s and t = 0.01 s

To find: Average force (F)

Formula: F = \(\frac{m(v-u)}{t}\)

Calculation: From formula,

F = \(\frac{0.150[20-(-12)]}{0.01}\) = 480 N

The average force exerted on the ball by the bat is 480 N.
