5. [-/4 Points] DETAILS SERCPWA11 5.WA.026. MY NO A force of constant magnitude pushes a box up a vertical surface, as shown in the figure. The box moves at a constant speed. If the mass of the box is 6.5 kg, it is pushed 2.7 m vertically upward, the coefficient of friction is 0.35, and the angle 0 is 30.0, determine the following. (a) the work done (in ]) on the box by F (b) the work done (in ]) on the box by the force of gravity (c) the work done (in j) on the box by the normal force J (d) the increase in gravitational potential energy (in J) of the system of the box and earth as the box moves up the wall 6.

MY NOTES PRACTICE AN While leaning out a window that is 5.7 m above the ground, you drop a 0.60 kg basketball to a friend at ground level. Your friend catches the ball at a height of 1.8 m above the ground. Determine the following. (a) the amount of work done (in ]) by the force of gravity on the ball (b) the gravitational potential energy (in ]) of the ball-earth system, relative to the ground when it is released c) the gravitational potential energy (in ]) of the ball-earth system, relative to the ground when it is caught (d) the ratio of the change (PE - PE.) in the gravitational potential energy of the ball-earth system to the work done on the ball by the force of gravity APE W 7.
