Work energy theorem problems with solutions pdf.

The cannons on 19th century frigates were ponderous things. If the foam applies an average resistive. If the net force applied by the truck ramp in the previous question is 300 000 n how far along the ramp will the truck move as it stops. Use the work energy theorem.

How much work is required to move it at constant speed a 3m along the floor against a friction force of 4n b 3m along a. The number of times n signifies that the particle will come to a rest at the center of the flat. Download work energy power problems with solutions pdf 497 kb equella is a shared content repository that organizations can use to easily track and reuse content. Work energy theorem the video introduces the work energy theorem provides the definition of the work energy.

Work energy solutions energy 1. If the puck slides twice as far the friction does twice as much negative work. It explains that when work is done on an object energy is transferred from one form to another. A body of mass 500g moving with 10ms 1 increases to 20ms 1 when acted upon a force find i the chane on kinetic energy ii the work done by the foorce iii name the theorem based on the same asked by rsankit1221 11th july 2019 9 35 pm.

Solution f mg 2 x 105 9 8 1 96 x 106 n applied force is equal to the weight of the water. Calculate the kinetic energy of this mass of water when entering the turbine. Work energy theorem practice problems name ate 5. For example on the uss constitution a frigate used in the war of 1812 the cannons were 3 meters 3 mbox meters 3 meters long had a mass of 3000 kg 3000 mbox kg 3 0 0 0 kg and could fire a 10 kg 10 mbox kg 1 0 kg cannonball up to a kilometer away.

In the diagram below the spring has a force constant of 5000 n m the block has a mass of 6 20 kg and the height h of the hill is 5 25 m. A 2kg crate rests on the floor. A 40 kg gymnast somersaults into a foam ball pit at a speed of 7 m s. Work and energy page 1 of 5 please ignore air resistance treat all surfaces as frictionless unless otherwise specified or implied.

Needless to say the recoil on the cannons was tremendous and a mechanism had. Determine the compression of the spring such that the block just makes it to the top of the hill. Doubling the speed quadruples the kinetic energy so the work by friction to reduce the kinetic energy to 0 make it stop must also increase by a factor of 4. Apply the work energy theorem.
