A roller-coaster car has a mass of 1120 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 21 m, its speed is not changing. (a) At the top of the hill, what is the normal force (using the negative sign for the downward direction) FN on the car from the track if the car's speed is v = 7.6 m/s? (b) What is EN if v = 19 m/s? Use g=9.81 m/s².

A 20-Mg train is traveling at a speed of 50 m/s at an angle of 10o. But the driver noticed that the bridge 300-m ahead is missing. At once, he pulls the break, thus applying a frictional resistance of Ff = 1000 N. At the same time Super Botting pushes back the train with a force of Fs=(123)d +100, where d is the distance that the train travels before stopping. Determine the stopping distance d, and mention whether or not Superperson would be able to save the train.
Suppose the total resistive force R to the motion of a car moving in a straight lineis directly proportional to its speed, i.e. R = kv where k is a constant.

(B) A maintenance man (climber) tries to maintain one of the power stations iocated at the top of the mountain in the situation of winter. During his work and by mistake drops his water bottle which then slides 100 M down the side of a steep icy slope to a point which is 10 m lower than the climber's position. The mass of the climber is 60 kg and his water bottle has a mass of 500 g. 1) If the bottle starts from rest, how fast is it travelling by the time it reaches the bottom of the slope? (Neglect friction.) What is the total change in the climber's potential energy as she climbs down the mountain to fetch her fallen water bottle? i.e. what is the difference between her potential energy at the top of the slope and the bottom of the slope? Analysis all the above situation.
In the figure, the 200-lb crate is being pulled up the slope by the motor M. If the velocity of the point P is 2s³ ft/s (where s is the displacement of the crate), and the coefficient of kinetic friction between the crate and the slope is u = 0.2, what will the towing force applied by M be when the box has moved 10 ft up the slope?
