Question 1 (1 point) A student is pushing toward the left on a heavy box that is resting on a rough surface. The box is not What forces are acting on the box and in which directions? force of gravity [down] and applied force [left ] 2 force of gravity [down], normal force [up], and applied force [left] force of gravity [down], normal force [up], force of friction [left], and applied force [left] 5 force of gravity [down], normal force [up], force of friction [right], and applied force [left]Question 2 (1 point) Person A and person B are pulling on an object unearthed at an archeological dig. They are using ropes at an angle of 30 from the forward position. Each person pulls with a force of 70 N. The force of friction on the stone is 100 N. What is the net force on the stone? backward forward 309 300 21 N [ forward] 30 N [backward] 39 N [backward] 240 N [forward]Question 14 (2 points) A 360 kg box rests on the bed of a truck that is going down a slope on a straight section of road. The truck starts down the slope with a speed of 100 km/h and slows to 60 km/h in 20 s. Assume that the acceleration is constant during this interval and calculate the strength and direction of the resultant force that must act on the box during this period of time.

A horizontal force is applied to one block as shown in Figure. mi a. If m1 = 2.0 kg and m2 = 1.0 kg and F = 3.0 N, find the force of contact between the two blocks. b. If the same force is applied to my rather than to m1, do you think the force of contact is the same value derived in (a)? What is that?Question 17 (4 points) A 5.0 kg block is pulled along horizontal frictionless floor by a cord that exerts a force F = 12 N at an angle 0 = 250. a. What is the acceleration of the block? b. If the force F is slowly increases, what is the value of F just before the block is lifted off the floor? C. What is the acceleration of the block just before it is lifted off the floor
