Answer:
Cricket ball,
u = 0 m/s
Mass = 80 g
= 0.08 kg
Connection between ball and bat = 0.08 s
S = 100 m
Time to cover the distance = 1.8 s
S = ut+0.5at²
S = 0.5at²
100 = 0.5at²
100/0.5t² = a
= 100/(0.5*1.8*1.8) = a
= 100/1.62 m/s² = a
= 61.72 m/s² = a
F = ma
= 0.08*61.72 N
= 4.93 N
Hope this helps.
