Three applied forces, F1= 20.0 N, F2= 40.0 N and F3= 10.0 N act on an object with a mass of 2.00 kg which can move along an inclined plane. The questions refer to the instant when the object has moved 0.600 m along the surface of the inclined plane in the upward direction. Neglect friction and use g=10.0 m/s^2.
What is the amount of work done by force F1 as the object moves up the inclined plane?
What is the amount of work done by force F2 as the object moves up the inclined plane?
What is the amount of work done by the force F3 as the object moves up the inclined plane?
What is the amount of work done by the gravitational force as the object moves up the inclined plane?
A 9.22 kg ball, hanging from the ceiling by the light wire 145.00 cm long, is struck in an elastic collision by a 1.20 kg ball moving horizontally at 6.46 m/s just before the collision.
if the boy is traveling at 1m/s relative to the ground, explain how fast does the boy appear to be moving relative to the woman?
A charged object has a potential of 40 V at a distance of 3 m. If the distance is increased to 42 m, then what will be the new potential
At its Ames Research Center, NASA uses its large "20-G" centrifuge to test the effects of very large accelerations (hypergravity) on test pilots and astronauts. In this device, an arm 8.84m long rotates about one end in a horizontal plane, and the..
