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.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
