A cart weighing 420 N rests on a 23° incline. Calculate the component of its

weight that presses the cart to the hill.

You push a 560 mm radius bicycle wheel, which is approximately hoop shaped, along a flat region until it reaches a speed of 5.01 m/s. It then goes up a smooth hill of irregular shape and height 0.

In short-track speed skating, the track has straight sections and semicircles 16 m in diameter. assume that a 64 kg skater goes around the turn at a constant 13 m/s. what is the horizontal force on the skater?

The total thermal energy needed to raise the temperature of this ice cube to 0.0 °C and completely melt the ice cube is 5848 J specific latent heat of fusion of ice = 334 000 J/kg Calculate the mass of the ice cube.

How do Black Holes work?

If s car can drive 40m/s, then how long will it take to travel 2400m?

If a 1.50 kg mass revolves at the end of a string 0.50 m long, and its tangential speed is 6.0 m/s, calculate the centripetal force.

Balanced forces can change an object's direction. A. True B. False

Temperature is usually measured in degrees with a (n)

Two lab carts are pushed together with a spring mechanism compressed between them. Upon release, the 5.0 kg cart repels one way with a velocity of 0.12 m/s. The 2.0 kg cart goes the other way. At what velocity does it travel?
