What is the definition of work? What is the definition of energy? A box of mass 30kg is released from rest when the length of the spring was 0.4m. The spring’s constant is 500 N/m and its natural length is 0.7m. The coefficient of friction between the box and the floor is 0.25. Using the work-energy method, Determine the forces that don’t do work, Determine the velocity of the box when the spring becomes unstreteched, The total distance traveled by the box from start until it comes to rest.

A cyclist is riding a bike at 6.50 m/s on a horizontal track. The cyclist and their bike have a combined mass of 98 kg. How much work will be required for the cyclist to increase their speed to 10.0 m/s? Give your answer to the nearest Joule. Do not include units in your answer.
In the pitching motion, a baseball pitcher exerted an average horizontal force of 80 N against the 0.15 kg baseball while moving it through a horizontal displacement of 2.2 m before he released it. How much work did the pitcher do to the baseball as a result of this force? If the baseball’s velocity at the start of the pitching action was zero, how fast was the ball moving at the instant of release?
You are throwing a ball to a friend while taking physics and begin to wonder about work. You know that when you throw, you exert a force of 655 N on the ball (which has mass 1.84 kg), and that you do so for a distance of 0.27 m. If you start the throw from rest, what is the final speed of the ball? When you show your work for this question, you must do the calculations using work and energy for credit. If you use kinematics you will not recieve credit. Your Answer: units Answer
A mass of 2 kg is separated from a wall via a spring (k=1500 N/m). You manage to compress the spring 1.3 meters before it slips through your hands and launches across the floor. If there is a coefficient of kinetic friction of 0.25 between the block and the floor, how much force is friction applying to the block? How far will the block travel before coming to a stop? How much work did friction do on the block?
