Hheellppp its !
just answer b and c

B.  F = 7.35 N

C.  Equal and opposite

Explanation:

Given

The mass of the football, m = 0.42 Kg

Time of flight of the ball, t = 1.6 s

The initial velocity of the ball, u = 0

The final velocity of ball, v = 28 m/s

The acceleration of the ball is given by the formula

                                       a = (v - u) /t m/s²

Substituting the values in the above equation

                                        a = (28 - 0) / 1.6

                                           = 17.5 m/s²

The force on the ball is given by the formula

                                       F = m x a  newton

Substituting the values in the above equation for force

                                      F = 0.42 Kg x 17.5 m/s²

                                        = 7.35 N

Therefore the force acting on the ball is, F = 7.35 N

According to newton's third law of motion, if a person exerts a force on a ball, the ball also exerts a force that is equal to applied force on the person's foot. It is in a direction opposite to the force exerted by the kicker's foot.

Hence, the forces are equal and acting in opposite direction.
