Option a. The total force that is calculated is given as 24 n/s
<h3>How to solve for the magnitude</h3>
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
