A 1200 kg frictionless roller coaster starts from rest at a height of 17 m. What is its kinetic energy when it goes over a hill that is 10 m high?
A 1200 kg frictionless roller coaster starts from rest at a height of 20 m. What is its kinetic energy when it goes over a hill that is 11 m high?
Consider the roller coaster pictured. The coaster car (m= 1000 kg) starts from rest at (1) the top of the first hill at height H = 40 m. It then (2) drops, (3) goes over the second hill assume semicircular) of height L, and (4) around the loop of radius R, all frictionless. After finishing the loop (5), it encounteres frictional resistance u = 1 on the track at and (6) hits an armadillo (mA = 5 kg) at distance...

A roller coaster starts at some height that you do not know. It goes down this hill and then goes up a second hill that is 29.7 m above the first drop. At the top of this hill, it has a speed of 28.5 m/s. So how high was the initial hill?
In the figure, a frictionless roller coaster car of mass m = 637 kg tops the first hill with speed v0 = 19.3 m/s at height h = 37.2 m. How much work does the gravitational force do on the car from that point to (a) point A, (b) point B, and (c) point C? If the gravitational potential energy of the car-Earth system is taken to be zero at C, what is its value when the car is at...
PLEASE SHOW WORK! A roller coaster starts from rest at a height h at the left side of a loop-the-loop, as shown in the figure. It is not attached to the track in anyway, and there is no friction from the track or from air resistance. If the radius of the loop is R = 6.0 m, what is the minimum height h for which the roller coaster will not fall off the track at the top of the loop?...
a mass of 200 kg travels down a frictionless roller coaster from a height of 50 m. When it reaches the level ground (height 0 m) it encounters an unstretched horizontal spring with spring constant 10,000 N/m. As the mass comes to a rest how far does it compress the spring?
A 120 kg roller coaster starts from rest at point A and slides down the frictionless loop-the-loop shown in the accompanying figure. a) How fast is this roller coaster moving at point B? b) Calculate the normal force exerted on the car at point B B 24.00 m 25.0 m 12.0 m 3.00 m Upload your answer/solution once you finish each given problem.
In the figure, a frictionless roller coaster car of mass m -828 kg tops the first hill with speed vo -17.0 m/s at height h 42.0 m. What is the speed of the car at (a) point A, (b) point B, and (c) point C? (d) How high will the car go on the last hill, which is too high for it to cross? Use g-10 m/s2 .4 lirst hill h/2
