Abarefoot field-goal kicker imparts a speed of 44 m/s to a football initially at rest. if the football has a mass of 0.49 kg and the time of contact with the ball is 0.028 s, what is the magnitude of the force exerted by the ball on the kicker's foot? answer in units of n

The magnitude of the force exerted by the ball on the kicker's foot is of 769.99 Newtons.

Explanation:

Mass of the football = 0.49 kg

Initial velocity of the ball ,u= 0 m/s

Final velocity of the ball ,v= 44 m/s

time of contact ,t = 0.028 seconds

First law of motion:

v=u+at

The magnitude of the force exerted by the ball on the kicker's foot is of 769.99 Newtons.

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
