CP Riding a Loop-the- Loop . A car in an amusement park ride rolls without friction around a track ( Fig. P7.42 ). The car starts from rest at point A at a height h above the bottom of the loop. Treat the car as a particle. (a) What is the minimum value of h (in terms of R ) such that the car moves around the loop without falling off at the top (point B ?)? (b) If h = 3.50R and R = 14.0 m, compute the speed, radial acceleration, and tangential acceleration of the passengers when the car is at point C . which is at the end of a horizontal diameter. Show these acceleration components in a diagram, approximately to scale.

A matchbox car track begins at a height y=1.0, goes down hill to y=0, goes around a vertical loop of radius 0.2 m and then goes back up a smaller hill to end at a height y=0.3 m. The speed of the car at the end of the track is closest to which value?
a solid brass ball of mass 0.280 g will roll smoothly along a loop-the-loop track when released from rest along the straight section. The circular loop has radius R = 14.0 cm, and the ball has radius r < R. (a) What is h if the ball is on the verge of leaving the track when it reaches the top of the loop? If the ball is released at height h = 6.00R, what are the (b) magnitude and (c) direction of the horizontal force component acting on the ball at point Q?
A ball of uniform mass M=6.00kg and radius R, rolls smoothly from rest down a ramp at angle (theta)=30.0 degrees
(a) The ball decends a vertical height h=1.20m to reach the bottom of the bottom of the ramp. What is the speed at the bottom?
(b) What are the magnitude and direction of the frictional force on the ball as it rolls down the ramp?
