A roller coaster with mass (m=2500kg) has a speed of 10 m/s as it goes over a 13 m hill. When it reached the crest of a second hill 8 m tall, it is traveling at a velocity of 13 m/s. How much work did friction do on the coaster?

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?

A 4,500-kg roller coaster cart has a speed of 4.76 m/sm/s when it reaches its first peak at a 99.0 mm height from the ground level. After descending, it climbs up the second hill which is 84.2 mm above the ground level. How fast is the roller coaster cart at the top of the second hill? Assume there is no friction with the rails and no air resistance during the cart's motion.

Imagine a roller coaster that starts at the top of a big hill, and goes immediately into a loop-the-loop. If the mass of you and the cart is 50 kg, and the loop is 30 m tall, how high does the hill have to be so that you make it through the loop without falling off? Assume there is no friction. Be exact in your calculation.
