4. A pinball of mass M and radius R is pushed against a spring of spring constant k. The spring is compressed a distance D and the pinball machine ramp is inclined at an angle 0. The spring is then released. The pinball is a solid metal sphere that rolls without slipping. a. Determine the speed of the pinball as it leaves the spring. Hint: the spring force is not constant so you cannot use constant acceleration kinematics. Use conservation of mechanical energy instead. b. What is the distance that the pinball would go up the ramp before coming back down?

2. With the application of Newton's Law: A canonical pendulum is a mass on the end of a cord, where the mass moves at a constant speed in a circular path while its cord traces out a cone. Suppose the length of the pendulum is 1.2 m moving in circle of radius 0.2 m. What is the period of the pendulum? Please answer correctly, comprehensively, and completely. Because based on experience, some expert answers were wrong. Thanks a lot!
A large solid disk with radius rb= 1.1m has a second, smaller solid disk with radius rs= 0.32m and mass ms= 3.5kg attached to it. Wrapped around the smaller disk is an ideal string with a hanging mass mh= 2.3kg attached to it. The hanging mass starts out a distance yi= 5.2m above the ground as shown in Figure 1, and falls towards the ground with constant speed. a) What is the torque about the center of the pulleys? Remember torque is a vector. b) What should the mass of the larger pulley be such that the system of pulleys has an angular acceleration of α = 1.2rad/s ? c) How long will it take the hanging mass to hit the ground?
A1 kg mass is tied to a string and is being swung in a horizontal circle. The mass has a constant angular velocity of 0.3 rad/s. The string has a Young's modulus of 10 X 106 N/m?, and the string's original length is 0.7 m long. The radius of the string is 0.05 cm. How much does the string stretch? You can think of the string as being shaped like a long, thin cylinder. 5.6 mm 2.7 mm 3.2 mm 4.7 mm 3.8 mm
