The force is -12,000 N
Explanation:
First of all, we calculate the acceleration of the ball, by using the following suvat equation:
where:
v = 0 is the final velocity of the baseball (it comes to rest)
u = 40 m/s is the initial velocity
a is the acceleration
s = 2.0 cm = 0.02 m is the displacement of the ball
Solving for a,
Now we can calculate the average force exerted on the ball, by using Newton's second law:
where
m = 300 g = 0.3 kg is the mass of the ball
is the acceleration
Substituting,
where the negative sign indicates that the direction of the force is opposite to the direction of motion of the ball.
