Suppose that you want to move a heavy box with mass 30.0 kg across a carpeted floor. You try pushing hard on one of the edges, but the box does not move. Suppose that you are pushing against the box from an angle 30.0 degrees above horizontal with a force of magnitude 240 N. What is the magnitude of the friction force acting on the box?

A store clerk moves a 4.4 kg box of soap at a constant velocityalong a shelf by pushing it with a horizontal force of magnitude8.1 N. The clerk does 5.9 J of work on the box.

(a) How far did the box move?

(b) What was the magnitude if the force of kinetic friction duringthe push?

(c) How much work was done by the force of kinetic friction on thebox?

find the box's speed vf at 3.0 s after you first started pushing on it.

A box of mass 3.06 kg slides down a rough vertical wall. The gravitational force on the box is 30 N . When the box reaches a speed of 2.5 m/s , you start pushing on one edge of the box at a 45? angle (use degrees in your calculations throughout this problem) with a constant force of magnitude Fp = 23 N , as shown in (Figure 1) . There is now a frictional force between the box and the wall of magnitude 13 N . How fast is the box sliding 2.8 s after you started pushing on it?
