You push a box of mass 20.6 kg with your car up to an icy hill slope of irregular shape to a height 4.3 m. The box has a speed 12.3 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) to a flat area before sliding into a box larger box of mass 19 kg. The boxes then fall off a sheer cliff together to the ground (with no drag). (a) What is the velocity of the pair just before hitting the ground? { Coordinate Form } (b) What is the velocity of the pair just before hitting the ground? { Vector Form } 2) (c) How much energy Is lost in the process?

A box with a mass of 3000 g slides down the slope. The slope is inclined at an angle of 30 degrees and has a length of 1 meter. The box starts from rest at the top, experiences a constant force of friction with a magnitude 5.00 N, and begins to travel a short distance to the horizontal floor after leaving the slope. Calculate the box's speed at the bottom of the

A 40.0-N crate starting at rest slides down a rough 6.00-m-long ramp, inclined at 30.0 degrees with the horizontal. The magnitude of the force of friction between the crate and the ramp is 6.0 N. What is the speed of the crate at the bottom of the incline?
WORK ENERGY AND POWER COMPLETE SOLUTION A 2kg block hits the spring with a speed of 4 m/s. Determine the total distance traveled by the block before it comes to stop if the spring constant is 8 N/m, and the coefficient of static and kinetic friction is 0.50 and 0.45, respectively.
In the given figure below, a 3.0 -kg block is sliding down a 60o-rough incline. The speed of the block is 1.68 m/s at the instant it is 5.25 m from an uncompressed spring located at the other lower end of the incline. The spring has a spring or stiffness constant of 120 N/m and the coefficient of kinetic friction between the block and the incline is 0.35. (a) At what speed (in m/s) will the block strike the spring? (b) What would be the maximum compression (in m) of the spring?
A light plane of mass 1200 kg makes an emergency landing on a short runway. With itsengine off, it lands on the runway at a speed of 35 m/s. A hook on the plane snags acable attached to a 130 kg sandbag and drags the sandbag along. Now you can consider thesystem as a combined mass along with the sandbag and the plane.Now, the coefficient of friction between the sandbag and the runway is μk = 0.4, and also theplane’s brakes give an additional retarding force of magnitude 1400 N. So our target for thisproblem is to find how far does the plane go before it comes to stop.Assume, when the plane snags the sandbag, the collision is instantaneous.[Hints Think carefully whether you can apply conservation of momentum or not] Find the speed of the plane and sandbag immediately after the collision.
An aeroplane required for take off speed of 80 km/h, the run onthe ground being 100m. The mass of the aeroplane is 10000 kgand coefficient of friction between the plane and ground is 0.2.Assume that the plane accelerates uniformly during the take off.What is the maximum force required by the engine of the plane fortake off.
A bicycle and rider, travelling at 12 km/h on a level road, have a mass of 105 kg. A brake is applied to the rear wheel which is 800 mm in diameter. The pressure on the brake is 80 N and the coefficient of friction is 0.06. Find the distance covered by the bicycle and number of turns of its wheel before coming to rest.
Person A lifts a 10 kg box vertically upward to a height of 2 meters. Person B pushes 10 kg box up an inclined ramp with friction to a height of 2 meters. Which person used more energy to get the box to a height of 2 meters? - person B - they both used the same amount of energy - you can't tell because it depends on how much time it took for each person - person A
