A toy shop owner is designing a display for his store window. mear He would like a snowman on a sled to travel in a circular path of radius d on an icy (frictionless) surface. To make this happen, he attaches a string to the sled, passes the string through the center of a vertical pole, and anchors the other end of the string to a teddy bear, a distance L from the pole, on a different level. He will give the sled a little push to get it m started traveling at a constant speed v. Since he might want to sell the bear later, he will not glue it down and has to rely on the friction between the bear and the surface, which has a coefficient of static friction µ. If the mass of the snowman and sled combined is m, what is the minimum mass of the bear mpear for which this motion is possible? Express your answer in terms of m, L, d, u, v, and g (the acceleration due to gravity). mbear 2

And don't worry about whether the passengers would actually survive the trip. They are lightweight crash test dummies. NTC A cart of mass m= 347 kg is going around a circular loop-the-loop. There is no motor. The cart moves only under the influence of gravity. Ignore friction and let g = 9.81 meters per second squared. The loop has a radius of r meters. When the cart is at the top of the loop, the normal force on the cart (exerted by the track) pushes down on the cart with a force of N = 1,330 newtons. When it is at the bottom of the loop, the cart has a speed of 30.7 meters per second. What is the radius of the loop (in units of meters)?
