Assuming negligible friction, rank the carts from greatest to least achieved vertical height given the weights and velocities shown. 2 ft/s 3 ft/s А 2 lb 1 lb 1 ft/s 4 ft/s C D 4 lb 3 lb Which cart will have the least cart height achieved?The Colussus is a ferris wheel at 6 Flags amusement park with a 50.4 m diameter. It rotates at 1.5 rpm. For the following, assume the rider has a mass m = 65 kg, and that the rider sits forward with feet up so the only part of the seat that exerts a force on the rider is the horizontal seat bottom. As usual, a free body diagram is a great place to start. Find the normal force exerted by a seat on a person riding the Colossus at the highest point in the ride. Hint: the speed of the rider can be computed from the circumference of their circular path and the time it takes to make one full revolution. Find the normal force exerted by a seat on a person riding the Colossus at the lowest point in the ride.
- A car of mass m is negotiating a circular turn of radius R and speed v on a banked road with an angle of banking θ. The forces on the car are shown below. Ignore friction in this problem. Draw a free body of the car. Identify and show the radial direction. Pick coordinate axes with x pointing in the radial direction towards the center of the circle and y in the vertical direction. Show the coordinate axes on the free body diagram. Set up Newton’s Laws in the radial and vertical direction. Which force provides the centripetal force? Use the equations in part C to solve for the speed of the car in terms of R, Does the speed depend on the mass of the car? If R=250.0 m, m=750.0 kg, calculate the speed of the car.You are in charge of designing a roller coaster that must have a speed of 26.9 m/s at the bottom of a loop the loop, like point A shown. If you want to ensure that the normal force acting on your passengers at this location is no more than 7637 N, what should the radius of the curvature in m be? Average mass of passenger = 286 kgA student of a mass of 96kg takes a ride in a loop-the-loop at an amusement park. The radius of the loop-the-loop is 21 meters. The normal force of the seat on student at the top of the loop-the-loop is 444 N. Find the speed of the student at the top of the loop-the-loop.
- Modified from the AP College Board Engineers are tasked with designing a new solar system themed roller coaster ride. The track starts at Point P, at the top of a sphere with radius R (representing Jupiter). The track goes down to ground level, then to Point Q, the top of a sphere of radius r (representing Neptune) and then back to the ground level. Ignore air resistance, and assume friction between the cart and the track is negligible Jupiter Radius R Neptune radius rThe 7.4 lb block has a speed of V = 2.4 ft/s to the left when the force of F = (3.6t3) lb is applied to the right.
