Option a. The total force that is calculated is given as 24 n/s

How to solve for the magnitude

300 g = 0.3kg

Force = change in momentum / time

We have to find the mass x velocity

0.3 x 40 = 12kg m / s

This rubber ball is said to strike and also rebound immediately. We can take the time as 1 second.

Force 1 x 12

= 12 N

The force that is exerted after the rebounding has occurred is also 12 N following Newton's 3rd law.

The total force that is exerted would be calculated as 12N + 12N = 24 N/S
