A small block of mass ?m is placed halfway up on the inside of a frictionless, circular loop of radius ?,r, as shown. The size of the block is very small compared to the radius of the loop. Determine an expression for the minimum downward speed ?minvmin with which the block must be released in order to guarantee that it will make a full circle.

box with mass m goes down a ramp that makes an angle of 60 º with the horizontal. The ramp bands together to a flat section and then onto a circle track of radius R that ends where it's vertical. box is released from rest at a distance 3R above the horizontal and leaves the track at point A. all surfaces are frictionless. What force does the track exert on the box before it leaves the track?
In designing amusement park rides, a car of mass 95.7 kg is released from a height 49.6meters and then slides on a friction less surface that becomes a vertical circle of radius 11.6. Whats is the maximum height, the car will not loose contact with the track at the highest point A in the circle? (Please submit your answer to 2 decimals) R
A father places his 20 kg child on a 5.0 kg cart, to which a 2.0 m rope is attached. He then holds the rope and spins the cart in a circle around him, keeping the rope parallel to the ground. If the Tension in the rope is 100 N, what is the cart’s speed v? Neglect friction.
A small object of mass m starts at rest at the upper left end of a curved frictionless track that contains a circular loop of radius R. What is the smallest value of y that will allow the object to reach the top of the circular loop as shown below? (Hint: the object will just lose contact with the track.) y R R
A frictionless block of mass 0.5 kg slides down a ramp of height 0.2 m and onto a horizontal frictionless table. A circular frictionless wall forces the block to move in a circular path. If the radius is 0.5 meters, calculate the time it takes the block to get from P to A, 1/4 the way around the circle.
A roller-coaster car is released from rest from height h and then moves freely with negligible friction. The roller-coaster track includes a circular loop of radius R in a vertical plane. A) First suppose the car barely makes it around the loop; at the top of the loop, the riders are upside down and feel weightless. Find the required height of the release point above the bottom of the loop in terms of R. B) Now assume the release point is at or above the minimum required height. Show that the normal force on the car at the bottom of the loop exceeds the normal force at the top of the loop by 6 times the car’s weight. The normal force on each rider follows the same rule. Such a large normal force is dangerous and very uncomfortable for the riders. Roller coasters and therefore not built with circular loops in vertical planes.

In a truck-loading station at a post office, a small 0.200 kg package is released from rest at point A on a track that is one-quarter of a circle with radius 1.60 m (Figure 1). The size of the package is much less than 1.60 m, so the package can be treated as a particle. It slides down the track and reaches point B with a speed of 4.40 m/s. From point B, it slides on a level surface a distance of 3.00 m to point C, where it comes to rest. Part A What is the coefficient of kinetic friction on the horizontal surface? V ΑΣΦ ?
