Unformatted text preview: (d) Does the block remain at rest or does the spring send it sliding back to the left? Explain. 2 2. An object of mass M is released from rest from a point P on the frictionless track shown. P is located a height h from the bottom of the track. (a) What is the object’s speed v at point Q (top of the loop) as a function of h ? (b) Draw a freebody diagram for the object at point Q. (c) What is the radial acceleration of the object at point Q given its speed computed in (a)? (d) There is a mininum value of h such that the object remains in contact with the track all the way around the circle. If the object is released from this height, what is the normal force on the object at Q? (e) What is the minimum value of h so that the object completes the loop without losing contact with the track?...
