You pull straight down on one side of a rope stretched across a pulley. Attached to the other side of the rope is a 10-kg box. How much force must you pull down on the rope to get the box to accelerate upward at a rate of 10 m/s2 ?
A cylinder has a moment of inertia, I. How much time does it take a torque, t, to increase its angular speed from w1 to w2?
An object, initially rotating with an angular speed of 15 rad/s, is subjected to a torque of 55 N.m that accelerates it constantly at 5.0 rad/s^2. What is the moment of inertia of the object?
Two satellites of equal mass orbit a planet. Satellite B orbits at twice the orbital radius of Satellite A. The gravitational force on Satellite A ................. that on Satellite B.
A boy pushes a 10-kg crate across the floor with a constant force of 10 N against a force of friction. The box accelerates at a rate of 0.1 m/s2. What is the magnitude of the opposing frictional force?
A space station is in orbit between the Earth and the moon. The force due to gravity on the space station from the moon is the same as the force due to gravity from the Earth. (FGmoon = FGearth). How far away from the Earth is the space station? How far f
given the diagram below, find the maximum m1 that will be in equilibrium with m2 and find T
A 2.0 m long uniform rod with a mass of 12 kg rotates about an axis through its center. There are applied forces as shown in the diagram below. The moment of inertia for a rod rotating about its center is given by I=(1/12)ML2 a) Assuming a counterclockwis
A desk of mass 45 kg is pushed across a rough surface (mK = 0.18) for a distance of 2.0 m by a constant force of 50 N. If the desk reaches a speed of 1.0 m/s by the end of the push, what was its speed at the beginning of the push?
A 20 m ladder, with a mass of 30 kg, is leaning against a wall with its base 10.0 m from the wall and at a slope of 65° to the floor. Because both the wall and the floor are frictionless, a rope is tied horizontally 1.00 m from the ladder to the floor. A
