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

Find the total area of the solid figure. 78 sq. in. 90 sq. in. 60 sq. in.
yaroslaw [1]

The total area of the figure will be 245 sq. in.

<h3>Total area of a cylinder</h3>

The figure is a cylinder and the total area of a cylinder is given by the formula below:

Total Area of a cylinder = 2πrh+2πr^2

Where r is the radius, h is the height of the cylinder, and π is constant with a value of 22/7.

In this case, looking at the image, the radius is 3" while the height is 10". Substituting these values into the formula above, we have:

Total Area = 22/7((2x3x10) + (2x3^2)) = 22/7(60+18)

           = 245 sq. in.

Thus, the total area of the solid figure is 245 sq. in.
