2. In the figure, a stunt car driver negotiates the frictionless track shown in such a way that the car is barely in contact with the track at the top of the loop. The radius of the track is 9.9 m and the mass of the car is 1800 kg. Find the magnitude of the force of the car on the track when the car is at point A. You can treat the car as a...

At an amusement park, a car of mass m rolls without friction around a track as shown. The car starts from rest at point A, a height h = 3R above the bottom of the loop (R is the radius of the loop). Treat the car as a point-like particle. (a) Draw the free body diagram for the car and find the car’s kinetic energy and normal force acting on the car at the top of the loop (point B)....

1. A roller coaster has a 300 kg car. Assume the track is frictionless. a) The car starts at a speed 20 m/s on a horizontal track. It then goes through a circular loop. What is the speed of the car when it is at the top of the loop, h = 10 m above the horizontal track? b) What is the normal force applied from the track at the point? Does this force point upward or downward? Assume the...

A ball rolls along the frictionless track shown in FIGURE P2.35. Each segment of the track is straight, and the ball passes smoothly from one segment to the next without changing speed or leaving the track. Draw three vertically stacked graphs showing position, velocity, and acceleration versus time. Each graph should have the same time axis, and the proportions of the graph should be qualitatively correct. Assume that the ball has enough speed to reach the top. Draw position, velocity,...

A hollow spherical ball is let go from the top of a track and goes around a circular loop (R = 60 cm). 23. What must be the minimum height of the track so that the ball will not fall off the track at the topmost point of the loop? R 24. When the above condition is met, what is the tangential speed of the ball when it reaches the topmost point?
