(8c8p4) In the figure, a frictionless roller coaster of mass 1000
kg tops the first hill at height, h = 28 m with
speed 8.55 m/s. How much work does its weight do on it
from that point to point A?
How much work does its weight do on it from that point to point B?
How much work does its weight do on it from that point to point
C?
If the gravitational potential energy of the coaster-Earth system is taken to be zero at point C, what is its value when the coaster is at point B?
If the gravitational potential energy of the coaster-Earth system is taken to be zero at point C, what is its value when the coaster is at point A?
Alright Buddy, If that worked for you... don't forget to give
THUMBS UP?.(that will work for me!)

Suppose there is no friction on a roller coaster, a man of 80 Kg mass decides to skate on this roller coaster, the man is located at the highest point that is 32 m high, wants to get a speed record when he arrives to the lowest point. Determine: a) How much is the mechanical energy at the highest point, and still not moving? b) How much is the mechanical energy at the lowest point of the roller coaster? c)...
In the figure, a small block of mass m = 0.040 kg can slide along the frictionless loop-the-loop, with loop radius R = 19 cm. The block is released from rest at point P, at height h = 6R above the bottom of the loop. How much work does the gravitational force do on the block as the block travels from point P to (a) point Q and (b) the top of the loop? If the gravitational potential energy of...
