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 car on a roller coaster starts at zero speed at an elevation above the ground of 20.8 m. It coasts down a slope, and then climbs a hill. The top of the hill is at an elevation of 14.77 m. What is the speed, in m/s, of the car at the top of the hill? Neglect any frictional effects; g=9.80 m/s2. A projectile is shot from the surface of Earth by means of a very powerful cannon. If the...

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.

When a roller coaster went upside down at the top of a loop with a radius 8.0m, a speed of 11.2m/s was required to make the coaster feel safe. A. Assuming that air resistance and friction are negligible , what speed will the roller coaster have when it is right-side up at the bottom of the loop? B. The roller coaster begins its trip by being pulled up the lift hill by a chain lift and dropped after it reaches...

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...
