Question

Ana exerts a force of 20 N on a volleyball that has a mass of 0.15 kg. What is the force that the volleyball exerts on Ana?

0.15 N
20 N
19.85 N
20.15 N

Answer 1

Given:-

• Force , F = 20 N

• Mass , m = 0.15 Kg

To Find:-

• Force ,F' exerted by volleyball on Ana.

Solution:-

As we know that Force is the product of mass and acceleration.

• F = m×a

Substitute the value we get

→ 20 N = 0.15×a

→ a = 20/0.15

→ a = 133.33m/s²

∴The acceleration of the volleyball is 133.33m/s².

Now we have to calculate the Force exerted by volleyball on Ana.

→ F' = m×a

→ F' = 0.15× 133.33

→ F' = 19.99 ≈ 20 N

∴The Force exerted by volleyball on Ana is 20 N.

You can also calculate the force exerted by ball on Ana . Using Newton's Third Law Of Motion.

The Newton Third Law Of Motion state that Every action has an equal and Opposite Reaction.
