After seeing a giant rock rolls into the highway, the driver slan emergency escape ramp. The angle between the ramp and the velocity v of the truck is 30.0 m/s right after entering the ramp ramp) is 0.720, then how far along the ramp does the truck trav *Use work-energy theorem to ver this question and assume

11.) A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. During this process, what is the work done on the cabinet by the normal force, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

hans is pulling on a rope to drag his backpack to school across the ice. he pulls upwards and rightward with a force of 22.9 newtons at an angle of 35degrees above the horizontal to drag his backpack a horizontal distance of 129 meters to the Right. Determine the work done upon the back(in joules)

Hi please help with the following: As shown in the figure below, a 50-N sled is pushed up a frictionless inclined plane (theta =30 degrees) by a force of F = 75N applied parallel to the ground. The sled is moved along the plane for 10.0 m. a. Find the work done by the normal force

A sled of 50 kg mass moves along a smooth horizontal surface at 7 m/s. The sled encounters a rough spot that exerts a force of -90 Nt on the sled.  Calculate: a) What is the acceleration of the sled? b) Calculate how much work is done by the frictional force on the sled if the patch is 15 m in length. c) What is the sled's final velocity as it leaves the rough spot?

An elevator is  pulled 4.00m upwards from rest with a rope under 13000N of tension. The weight of the elevator is 12000N What is the net force on the elevator? write Newton’s 2nd law as an equation then use it to find the acceleration of the elevator Use one of your uniform acceleration equations to find the speed of the elevator after it has gone the 4.00m  and round your answer as appropriate  Now write  the work -energy theorem  then use it to find the elevators final kinetic energy  and speed. Your answer should be the same as it was from part

please solve these

Use the work energy principle to calculate how far the car will travel before stopping. How far would the car travel if it were going twice as fast?
