Answer :
The maximum force (Fmax) from the bat which hits the ball with a speed of 40 m/s of weight 0.145kg is 5.8 N.
What is force?
A push or pull that an object experiences as a result of interacting with another item is known as a force. Every time two items interact, a force is exerted on each of the objects. The force is no longer felt by the two objects when the interaction ends. Only when there is interaction do forces actually exist.
Given,
mass of ball is 0.145 g.
speed of ball after being hit is 40 m/s.
maximum force =?
time taken to hit the ball be 1 s
By using the formula, F = ma
where,
F = force from the bat
m = mass of the ball
a = acceleration of the ball
But,
a = s/t
where,
s = speed of the ball being hit
t = time taken
F = ms/t
F = 0.145 x 40 / 1
F = 5.8
∴ force from bat is 5.8 N.
