# Question

An out-of-control truck with a mass of 5000 kg is traveling at (about 80 mi/h) when it starts descending a steep (15o) incline. The incline is icy, so the coefficient of friction is only 0.30. Use the work– energy theorem to determine how far the truck will skid (assuming it locks its brakes and skids the whole way) before it comes to rest.

If the work required to speed up a car from 10 km/h to 20 km/h is 5.0 x 103 J, what would be the work required to increase the car’s speed from 20 km/h to 30 km/h? The floor of the basement of a house is 3.0 m below ground level, and the floor of the attic is 4.5 m above ground level. (a) If an object in the attic were brought to the basement, the change in potential energy will be ...Referring to Fig. 3.13, find the speed with which the stone strikes the water using energy considerations. A simple pendulum has a length of 0.75 m and a bob with a mass of 0.15 kg. The bob is released from an angle of relative to a vertical reference line (Fig. 5.34). (a) Show that the vertical height of the bob when it is ...A 1.00-kg block (M) is on a frictionless, 20o inclined plane. The block is attached to a spring (k = 25 N/m) that is fixed to a wall at the bottom of the incline. Alight string attached to the block runs over a frictionless ...Post your question
