And don't worry about whether the passengers would actually survive the trip. They are lightweight crash test dummies. NTC A cart of mass m= 347 kg is going around a circular loop-the-loop. There is no motor. The cart moves only under the influence of gravity. Ignore friction and let g = 9.81 meters per second squared. The loop has a radius of r meters. When the cart is at the top of the loop, the normal force on the cart (exerted by the track) pushes down on the cart with a force of N = 1,330 newtons. When it is at the bottom of the loop, the cart has a speed of 30.7 meters per second. What is the radius of the loop (in units of meters)?
A speedboat with a mass of 505 kg (including the driver) is tethered to a fixed buoy by a strong 29.7 m cable. The boat's owner loves high speed, but does not really want to go anywhere. So the owner revs up the boat's engine, makes a lot of noise, and runs the boat in circles around the buoy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 12300 N, with what force is the boat's engine pushing the boat? Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m) × v², where v denotes the boat's speed. Ignore any drag force on the cable. force: N & TOOLS x10
The accompanying figure shows a frictionless channel in the shape of a segment of a circle with center at "O". The channel has been anchored to a frictionless horizontal tabletop. You are looking down at the table. Forces exerted by the air are negligible. A ball is shot at high speed into the channel at "p" and exits at "r." Consider the following distinct forces: A downward force of gravity. A force exerted by the channel pointing from q to O. A force in the direction of motion. A force pointing from O to q. Which of the above forces is (are) acting on the ball when it is within the frictionless channel at position "q"?
A 0.2-kg ball is attached to a rope and is swung in a horizontal surface that has negligible friction. The circular path is moves in has a radius of 0.6 m. If the ball makes 150 revolutions per minute, the tension force of the string is:
A roller coaster has a vertical loop with radius 27.2 m. With what minimum speed should the roller-coaster car be moving at the top of the loop so that the passengers do not lose contact with the seats?
A puck is sliding around a circular track that is banked at an angle ϕ with respect to the horizontal such that no friction between the puck and the track is required to keep the puck from slipping up or down the track. If the puck is moving at a speed 34.1 m/s and the radius of the track is 401 m, determine ϕ in degrees.

A 1.5-lb slider is propelled upward at A along the fixed curved bar which lies in a vertical plane. If the slider is observed to have a speed of 10.6 ft/sec as it passes position B, determine (a) the magnitude N of the force exerted by the fixed rod on the slider and (b) the rate v at which the speed of the slider is changing (positive if speeding up, negative if slowing down).

A small block of mass 1.26 kg slides without friction on a horizontal table. Initially it moves in a circle of radius Ro = 0.6 m with a speed 1.5 m/s. It is held in its path by a string that passes through a small hole at the center of the circle. The string is then pulled down a distance of 0.12 m.( Ro - R = 0.12 m.) It is pulled so slowly that the object continues to move in a circle of continually decreasing radius. 1) While the string in pulling in the block, which of the following qualities of the block is conserved (circle all that are correct): a) Rotational kinetic energy (b) Angular momentum c) Linear momentum d) Mechanical energy e) None of the above √/2) What is the final linear speed of the block (in m/sec)? 1.5 m/sec (3) How much work was done by the force that pulled on the string?0.915
