A/ Can someone help me, how can the third law of motion (Newton) help solve a problem / issue. be specific b/ how can pushing off a wall on a skateboard demonstrate the third law of Newton. If needed use gravity, friction, and air resistance.

c/ How can dropping a ball on the ground demonstrate the third law of Newton. If needed use gravity, friction, and air resistance.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

The answer would be d. hope this :

  soil is  vegetal. in forest or prairies, as well as agricultural fields, dead plants are transformed by different kinds of living organisms.
