Don't use : Ug= mgh please.

A roller coaster car (shown below) has a mass of 1000 kg when fully loaded with passengers. Point A is 20 m
below point 1 and point B is 25 m above A. Assuming that the way down is frictionless but not the way up,
and the speed of the car at point 1 is 20 m/s, determine the following:
Point 1
10.00
eni
141
Use conservation of energy to determine the speed of the car at point A.
(B)
b. Determine the force exerted by the car on the track at point A?
15 m

5. The N pole faces of two cylindrical neodynium magnets having a radius of 0.5 cm and a length of 20 cm are brought together so that their faces are parallel and there is a small gap between them. The magnetic surface charge density on each pole face is 2 x 10° Cm's. (a) What is the force between the magnets in the limit in which the gap goes to zero? -Assume that the magnets are much longer than shown in the figure below, so that you only need to concern yourself with the repulsion between N and N. (b) What is the force between the magnets when they are separated by 0.5 m? At this separation you can approximate the four pole faces as point-charges.
