Question 2 (10 points)

A football player kicks a ball with a mass of 0.5 kg. The average acceleration of the football was 15 m/s/s. How much force did the kicker apply to the football?

Question 2 options:

15.5 N


30 N


7.5 N


14.5 N

Answer 1

7.5N

Step-by-step explanation:

Given parameters:

Mass of the ball = 0.5kg

Acceleration = 15m/s²

Unknown:

Force exerted by the kicker = ?

Solution:

To know the force exerted by the kicker, we use the mathematical expression below:

Force = mass x acceleration

This is based on Newton's second law of motion;

Now insert the parameters and solve;

Force = 0.5 x 15 = 7.5N
