Problem 1 A motorcyclist wants to perform the “Wall of Death” stunt. In this stunt, the rider will drive a motorcycle around the inside of a circular, vertical wall (you can see examples of this on YouTube if you search for “motorcycle stunt wall of death”). If the rider moves too slowly, then friction will not be large enough to oppose gravity and keep the motorcycle from falling. Let’s do som calculations to help the rider out. (A) Draw a free body diagram of the motorcycle and rider while they are moving around the vertical wall. (B) For this particular stunt, the radius of the wall is r = 5.0 m, and the rider wants to go at a constant v = 14 m/s. What will the rider’s centripetal acceleration be? (C) How much larger is this than g, the accerelation due to gravity near the surface of Earth?

3. A double-inclined plane is shown here. The coefficients of friction are 0.30 for the left surface and 0.10 for the right surface. 10 kg 15 kg PIf the system is released from rest, what direction will it accelerate? а. Explain why or why not. Note: You do not need to make a 37° 53° calculation – use physical intuition! Think what would happen without friction and work from there. b. Now that you have the direction of the acceleration of the system, find the magnitude of the acceleration. Show your work, including FBDS. Note: Tilt your axes for both surfaces. Put the positive direction in the direction of the acceleration to take care of minus sign issues.

A student lets a toy car roll four times down a ramp that is 1 m long. Each time the student covers the surface of the ramp with a different material. The student measures the time it takes the car to roll down the ramp and records the results in the table below. Time to complete Material Ramp (s) 4 8 Y 5 Which of these would be the best conclusion based on the data in the table? O Different surfaces affect how fast a toy car accelerates. O Different toy cars travel at different speeds. O Gravity has little effect on the speed of toy cars on different surfaces. O Air resistance is the greatest factor in limiting the acceleration of different toy cars.
Fans at the Tour de France can be exceedingly annoying, often impeding the cyclists and sometimes causing wrecks. In1994 Laurent Jalabert crashed into a gendarme (policeman) and was seriously hurt.Sometimes riders can stop to avoid a collision, sometimes not. It depends on friction and reaction time. The 95-kg Jalabert was speeding at 40 mph along the level street on a wet day. The coefficient of kinetic friction between his wheels and the road was 0.13. He looked up to see the gendarme about 44 m (about half of a football field) ahead of him. If he has typical human reaction time (0.15 s), how close will he be to the gendarme when he begins to apply the brakes? Round the final answer to two decimal places. As Jalabert skids, what is the magnitude of his acceleration? Round the final answer to two decimal places. How fast was Jalabert going when he hit the gendarme? Round the final answer to one decimal place.

Problem 15. A frictionless track consists of a horizontal part of unknown length, which connects to a vertical semicircle of radius r as shown. An object, which is given an initial velocity e, is to move along the track in such a way that alter leaving the semicirele at the top it is to fall back to its initial position. What should the minimum length of the horizontal part be? r
Modern roller coasters have vertical loops like the one shown in the figure below.
