  1. How much work must be done to move a 19.8 kg chair 2.95 m across the floor at constant velocity if the coefficient of kinetic friction between the chair and the floor is 0.67 and you are pushing at an angle of 14.4o relative to the floor?

    J

  2. What height above the water does a 135.7 kg diver jumps need to jump from for gravity to do 6143 J of work on him/her?

    m

  3. How far must you pull a 33.3 kg box across the floor to do 2362 J of work if the coefficient of kinetic friction between the box and the floor is 0.77?

    m

  4. How much work is done by gravity when a 141 kg diver jumps from a height of 7.87 m into the water?

    J

  5. If you do 235.4 J of work to move a 10.2 kg chair 2.45 m across the floor at constant velocity, and you are pushing at an angle of 23.3o relative to the floor, what is the coefficient of kinetic friction between the floor and the chair?

  6. How much work must be done to move a 2.2 kg chair 4.9 m across the floor at constant velocity if the coefficient of kinetic friction between the chair and the floor is 0.37 and you are pushing at an angle of 23.2o relative to the floor?
