A 200-kg roller coaster reaches the top of the steepest hill with a speed of 5.60 km/h. It then descends the hill, which is at an angle of 25° and is 58.0 m long. What will its kinetic energy be when it reaches the bottom? Assume µk = 0.10. A boy pulls a 20.0-kg box with a 130-N force at 33° above a horizontal surface. If the coefficient of kinetic friction between the box and the horizontal surface is 0.29...
3. A roller coaster sits at the top of a hill and is preparing to enter a loop-the-loop as shown below. The hill has a height of 86.0 meters, the loop has a radius of 22.0 meters and the roller coaster has a mass of 525 kg. Assume h=0 at the bottom of the hill. a) What will be the velocity of the roller coaster when it reaches point C? A b) What will be the velocity of the roller...
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 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.
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 540 kg roller coaster has a speed of 21.0 m/s as it reaches the lowest point on the track, which is at the bottom of a vertical curve with a radius of 13.0 m. What is the force of the track on the vehicle at this point?
We are solving a roller coaster problem, We are only given the speed at which the roller coaster must be going at the bottom of the hill to make the loop. There is a hill in front of the loop and after it. We are trying to find the minimum height of the hill. speed is 44.7 m/s Then we have to figure out the maximum height of the loop to keep the cart in contact with it. I mainly...
