A baseball is thrown a velocity of 20 m/s. It takes the 20 kg ball 10 seconds 5 points
to reach the plate. What force is required? Hint: calculate acceleration
first. *

40 Newton

Explanation:

Mass of baseball = 20 kg

Velocity of baseball = 20 m/s.

Time taken for throwing = 10 seconds

Since acceleration is the rate of change of velocity per unit time

i.e Acceleration = velocity / time taken

Acceleration = (20 m/s / 10seconds)

Acceleration = 2m/s^2

Now, force required to throw the baseball is a product of mass and acceleration

i.e Force = Mass x acceleration

Force = 20 kg x 2m/s^2

Force = 40Newton

Thus, 40 newton of force is required to throw baseball to reach the plate
