A roller coaster ride begins the top of the second hill traveling 11 m/s. How fast will it be moving at the top of the 3rd hill if the 2nd hill was 8.6 meters higher. (g=9.8, units m/s, example: 13.1)
A roller coaster moving at 54 m/s begins from the bottom of a peak 69-m high. What is the speed of the coaster after descending 34 m from the peak? Use energy conservation and express your answer to 1 decimal place.

A roller-coaster track has six semicircular "dips" with different radii of curvature. The same roller-coaster cart rides through each dip at a different speed.For the different values given for the radius of curvatureR and speed v, rank the magnitude of the force of the roller-coaster track on the cart at the bottom of each dip.A) R=60m v=16 m/s B) R=15m v= 8m/s C) R=30m v= 4m/s D) R=45m v= 4m/s E) 30m v= 16 m/s F) R= 15m v=12 m/s
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...
A roller coaster begins to accelerate in the y direction at a rate of -4.9 m/s^2. what will be the downward force experienced by a roller coaster riding rein deer with a mass of 543 kg round your answer to four decimal places. Answer in units of N. Assume acceletation due to gravity is negative
A roller coaster of mass 80.0 kg is moving with a speed of 20.0 m/s at position A as shown in the figure. The vertical height above ground level at position A is 200 m. Neglect friction. a. What is the total mechanical energy of the roller coaster at point A? EA = b. What is the total mechanical energy of the roller coaster at point B? EB = c. What is the speed of the roller coaster at point...
4) When sitting in a roller coaster going through a vertical loop of radius of 8.5 meters, your "ap- parent' weight is the normal force provided by the seat, while your "true" weight is the gravitational force (which is unluckily unchangeable at mg) a) How fast must you be moving at the top of the vertical loop to achieve weightlessness (i.e., to have no apparent weight)? b) If moving at the same speed on the bottom of the vertical loop,...
A roller coaster begins at rest at the top of a 38 m hill. Find the velocity at a point 8 m above the bottom of the hill. Hint: PE at point 1 = (KE+PE) at point 2
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.
