A 30.0-kg crate is pushed across a rough floor by a horizontal force of 100 N of kinetic fiction between the crate and the floor is 0.100. If a total of 80.5 1 of work the crate, how far was it moved along the floor? done 21. Find the magnitude of the force ating on a 3.0-kg (assume all units in MKSo-ms cated at -2.0 m inside a potential 22. Which one of the following statements is false? More power...
A box is dragged 16 m across a level floor by a 75 N force acting at an angle of 35° to the surface. It is then dragged by the same force (same magnitude, same pulling angle) 8 m up a ramp inclined at an angle of 20% to the floor. Determine the total work done by the force.

a dog drags its bes box across a floor by applying a horizontal force of 4.5N. the kinetic frictional force acting on the box has magnitude 2.7N. As the box is dragged through 0.76m along the way, what are (a) the work done by the dogs applied force and (b) the increase in thermal energy of the bed and floor?
A 200 kg wagon with wheels so there is only a little friction is moved 10 m across a smooth floor by a force making a downward angle with the floor. The horizontal component of this force is a 5 N force acting parallel to the floor in the direction of motion and the vertical component of the force is a 10 N force acting perpendicular to the floor. The work done is?
A box of mass 6.0 KG accelerates from rest by a force across the floor at a rate of 2.3 m/s^2 for 5.0s. Find the net work done on the box if the weight is pulled up by a force of 85 N.
7. (20 pts) A force of 50 N is used to move a 5 kg box 30 m across a level floor. a. How much work was done on the box? b. If the movement takes 10 seconds, what is the average velocity of the box during the move? c. What is the average kinetic energy of the box during the move? d. What is the change in potential energy as a result of this move?
A storeho use worker pushes a box with a refrigerator (mass:96.0-kg) at constant velocity for a distance of 11.0 m. He pushes in the direction parallel to the horizontal floor. A 250.0-N frictional force opposes the motion of the box. Use Newtons second law and definition of work to answer the questions below. (a) (1 point) What is the acceleration of the box? as (b) (2 points) What is the net force, acting on the box? Write down Newtons second...

Force vs Displacement Force (N) 5 10 15 20 Displacement (m) 25 30 The graph above represents the force applied on a 5.00 kg box as it was moved across a floor. A. Calculate the total work done on the box. B. Determine the velocity of the box at the end of if it had an initial velocity of 2.00 m/s. C. What was the average power applied to the block if the whole displacement occurred...
A child pulls a block across the floor with force applied by a horizontally held string. A smaller frictional force also acts upon the block yielding a net force on the block that is smaller than the force applied by the string. How does the work done by the string compare with the change in the block’s kinetic energy? the work done is greater than the change in the kinetic energy of the block The work done is equal to...
Rachel is pushing a box across the floor while Jon, at the same time, is hoping to stop the box by pushing in the opposite direction. There is friction between the box and floor but you may ignore the effect of air resistance. Draw the force diagram for the box's motion and then choose the appropriate forces from the following list that should be included on the force diagram. Assume that the box is moving to the right during the...
