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:
4) À car travels around a curve banked at 10° to the horizontal. The radius of the curve is 90 m and the car is travelling at 61.2 km/h. Determine μs. 5) An Amazon package (2 kg) starts from rest, then begins to slide down a 4 m tall ramp that is inclined at 30°. The package then travels 12 m along a horizontal surface where it pushes into a spring (k = 3000 N/m). The package compresses the spring a distance x before coming momentarily to rest. Then the package is pushed in the opposite direction by the spring. The coefficient of friction between the ramp/floor and the package is 0.21. Calculate x and determine if the package will stop before it gets back to the ramp or if it will begin to slide up the ramp. h 6) A roller blader (84 kg) is travelling at 19 m/s [E]. A 21.2 kg child is riding a 7.8 kg bike at a speed of 6 m/s [W]. The roller blader and the cycling child collide in what can be assumed to be an elastic collision. What are the final velocities of the roller blader and the…
At amusement parks, there is a popular ride where the floor of a rotating cylindrical room falls away, leaving the backs of the riders “plastered” against the wall. Suppose the radius of the room is 7.9 m and the coefficient of friction between the rider and the wall is 0.839, what is the minimum the safe speed of the wall for the rider not to drop when the floor falls away. Use g=9.8 m/s2.

A small ball is attached to one end of light rope that has a length of 4.0 m. The other end of the rope is attached to the ceiling. The ball is held with the rope horizontal and released from rest. The ball moves in the motion of an arc of the circle. When the ball is at its lowest point, with the rope vertical, the tesion of the rope is 15.5 N. What is the mass of the ball?
The peripheral speed of the tooth of a 10-in.-diameter circular saw blade is 150 ft/s when the power to the saw is turned off. The speed of the tooth decreases at a constant rate, and the blade comes to rest in 9 s. Determine the time at which the total (or resultant) acceleration of the tooth is 130 ft/s?.
A road with a radius of 75.0 m is banked so that a car can navigate the curve at a speed of 16.8 m/s without any friction. When a car is going 36.8 m/s on this curve, what minimum coefficient of static friction is needed if the car is to navigate the curve without slipping?
An engineer wants to design an oval racetrack such that 3.20 × 10³ lb racecars can round the exactly 1000 ft radius turns at 1.00 x 102 mi/h without the aid of friction. She estimates that the cars will round the turns at a maximum of 175 mi/h. Find the banking angle necessary for the race cars to navigate the turns at 1.00 × 10² mi/h without the aid of friction. 0 = What additional radial force F, is necessary to prevent a race car from drifting on the curve at 175 mi/h? This banking and radius are very close to the actual turn data at Daytona International Speedway, where 3.20 × 10³ lb stock cars travel around the turns at about 175 mi/h. 0 Fr= N
