The centers of the Earth and its moon are separated by an average of 3.84 × 105 m and the moon’s mass is 7.35 × 1022 kg. What force does Earth’s moon exert on a 10 kg mass?
Terror Twins Steve and Phil are playing on a very large merry-go-round coated with ice (frictionless). mSteve =mPhil = 47.6 kg. The merry-go-round is spinning at a constant rate of revolution as the Terror Twins ride on it. Steve sitting 2.00 m from the center and must hold on to one of the metal posts with a horizontal force of 80.0 N to keep from sliding off. If Phil is sitting at the edge 4.00 m from the center, with what force must he hold on to keep from falling off?
A 560 g model rocket is on a cart that is rolling to the right at a speed of 3.0 m/s. The rocket engine, when it is fired, exerts a 8.0 N vertical thrust on the rocket. Your goal is to have the rocket pass through a small horizontal hoop that is 20 m above the launch point. At what horizontal distance left of the loop should you launch?

Two blocks, which can be modeled as point masses, are connected by a massless string which passes through a hole in a frictionless table. A tube extends out of the hole in the table so that the portion of the string between the hole and M1 remains parallel to the top of the table. The blocks have masses M1= 1.9 kg and M2= 2.8 kg. Block 1 is a distance r= 0.35 m from the center of the frictionless surface. Block 2 hangs vertically underneath. How much time, in seconds, does it take for block one, M1, to make one revolution? Assume that block two, M2, does not move relative to the table and that block one, M1, is rotating around the table.
You are in a carnival ride that consists of a circular room that spins around its center. You stand against the wall at the edge of the room. The room spins at a constant rate of one revolution every 5 seconds, and the room has a radius of 5 m. Your mass is 70 kg. After the room reaches it final speed, the floor drops out from beneath you, yet you remain stuck to the wall. What is the magnitude of the normal force exerted on you by the wall, and at what rate (power) does the normal force perform work on you? (Please explain the power that the normal force does work in detail.)

See Conceptual Example 6 to review the concepts involved in this problem. A 10.5-kg monkey is hanging by one arm from a branch and swinging on a vertical circle. As an approximation, assume a radial distance of 90.8 cm is between the branch and the point where the monkey's mass is located. As the monkey swings through the lowest point on the circle, it has a speed of 3.88 m/s. Find (a) the magnitude of the centripetal force acting on the monkey and (b) the magnitude of the tension in the monkey's arm.

One end of a string is wrapped several times around a pulley of mass 0.92 kgkg that is oriented vertically. The other end of the string is connected to a block of mass 0.35 kg, which is then slowly lowered until the string becomes taut. After which the person lets go of the block completely, thus allowing the block to descend and the pulley to rotate in unison. What is the magnitude of the acceleration of the block after the person has let go?
