    Four guys are pushing a 225 kg piano up a ramp into a moving van, and they are pushing with 1200N. Assume no friction. What is the final speed of the ramp is distance=3.5m and height is 1.2 m? Assume the same piano above, but this time there is friction, so the piano moves at a constant speed up the ramp at 20 degree angle, what is the coefficient of the friction?

    Two people lift either side of a piano which is d=3m wide. The piano is held at rest completely off the ground and is in its usual orientation with its top parallel to the ground. The person on the left exerts an upward force of FL=600 N, while the person on the right exerts an upward force of FR=900 N. At what distance x as measured from the left side, is the center of mass of the piano? Can someone...

    A 1290 -kg car is pushing an out-of-gear 2140 -kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4600 N . The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 770 N , including the "friction" of turning the truck's drivetrain. What is the magnitude of the force the car applies...

    Force 1. In the picture below, Jack is pushing a crate to the right. The crate is on very good wheels so friction between the crate and the floor is so small that it can be ignored. Jack pushes with a force of 120 N and the crate accelerates to the right at a rate of 1.0 m/s a In the picture at right, Jack and Janet are both pushing the same crate with a force of 120 N each....

    Suppose that you are asked to solve the following problem: Chadwick is pushing a piano across a level floor (see the figure). (Figure 1) The piano can slide across the floor without friction. If Chadwick applies a horizontal force to the piano, what is the piano's acceleration? To solve this problem you should start by drawing a free-body diagram. Determine the object of interest for the situation described. (options: The floor, Chadwick, or the piano)
