An Atwood's machine consists of blocks of masses m1 = 10.1 kg and m2 = 18.4 kg attached by a cord running over a pulley as in the figure below. The pulley is a solid cylinder with mass M = 8.30 kg and radius r = 0.200 m. The block of mass m2 is al
An 8.7 hour trip is made at an average speed of 73.0 km/hr. If the first third of the trip was driven at 96.5 km/hr , what was the average speed for the rest of the journey.
If the wad is traveling at 8 m/s when it hits and rod is 70 cm and has a mass of 3.5 kg, how what is the angular speed of the rod and putty after the collision?
A 116 kg chesterfield is pushed up a frictionless ramp at a constant speed by a delivery person. ff the ramp is inclined at 25.8° to the horizontal. What is the magnitude of the normal force that is exerted on the chesterfield by the ramp?
Stone is thrown straight up from the bottom of the cliff with a speed of 27.0 . The stone and ball collide part way up. How far above the base of the cliff does this happen?
After all the external forces are removed (so the compressed spring releases the mass) how far D along the plane will the block move before coming to a stop?
What is the tangential acceleration of a bug on the rim of a 11.0-in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 79.0 rev/min in 3.60 s? One second after the bug starts from rest, what is its centripetal accel
