A skier is being pulled up a smooth 25° dry ski slope by a rope which makes an angle of 35° with the horizontal . The mass of the skier is 75kg and the tension in the rope is 350N. Initially the skier is at rest at the bottom of the slope. The slope is smooth and g = 10 ms? Find the skier's speed after 5s.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
