a 1580 kg block of granite is pulled up an incline at a constant speed of 1.43 m/s by a cable and winch. The indicated distances are d1 = 46.3 m and d2 = 37.0 m. The coefficient of kinetic friction between the block and the incline is 0.395. What is the power due to the force applied to the block by the cable?
Assuming that the total retarding force on the diver is constant at 55.0 N with the parachute closed and constant at 3600 N with the parachute open, what is speed of the diver while he lands on the ground.

Heat engines take input energy in the form of heat, use some of that energy to do work, and exhaust the remainder. Determine the magnitude of the heat the athlete gives off
A ball rolling along at speed v without slipping on a horizontal surface while it comes to a hill that rises at a constant angle above the horizontal.
A stone takes 0.28s to travel past a window 2.2m tall. From what height above top of the window did the stone fall?
A proton moves perpendicularly to a uniform magnetic ?eld B with a speed of 1.9 × 10 ^7 m/s and experiences an acceleration of 8 × 10 12 m/s 2 in the positive x direction when its velocity is in the positive z direction. The mass of a proton is 1...
a block is pushed across a rough horizontal surface by a horizontal force of magnitude P= 25 . The coefficient of kinetic friction between the block and the ground is 0.3 if the blck started from rest
If the ball is released from rest at a height of 0.78m above the bottom of the track on the no-slip side, what is its angular speed when it is on the frictionless side of the track? suppose the ball is a solid sphere of radius 2.3cm and mass 0.14k..
The potential at location A is 393 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 781 V, and when released from rest from this spot, the particle arrives at B wit..
