Determine the acceleration due to gravity for low Earth orbit (LEO) given: MEarth = 6.00 x 1024 kg, rEarth = 6.40 x 106 m, G = 6.67 x 10-11m3kg-1s-2, and LEO is 400 km above Earth's surface.
How fast are objects in low Earth orbit (LEO) traveling given: MEarth = 6.00 x 1024 kg, rEarth = 6.40 x 106 m, G = 6.67 x 10-11 m3kg-1s-2, and LEO is 400 km above Earth's surface. Assume objects orbit with uniform circular motion.
A magnet (m = 0.3 kg) is stuck to the front door of your refrigerator. What is the magnitude of the magnetic force by the refrigerator on the magnet if the static friction force is at its maximum, and the coefficient of static friction is 0.5?
A 15-kg block slides on a frictionless table. It is connected by a massless string passing over a small frictionless pulley to a hanging 10-kg mass, as shown in the figure. The 15-kg mass is initially at rest. What will its acceleration be after it is released?
A 15-kg block slides on a frictionless table. It is connected by a massless string passing over a small frictionless pulley to a hanging 10-kg mass, as shown in the figure. The 15-kg mass is initially at rest. How far will the block move after 0.5 seconds?
A cylindrical room is rotating just fast enough so that blocks A and B do not drop. The coefficient of static friction between blocks A and B is 0.50. If block A is located 5 m from the axis of rotation, determine the minimum speed block A must travel so it does not fall down.

Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane
Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane and connected with a massless unstretchable string running over a massless, frictionless pulley to M2, which is hanging over the ground. The two masses are released initially from rest. The inclined plane has coefficients of static and kinetic friction μs and μk respectively where the angle θ is small enough that mass M1 , would remain at rest due to static friction if...
