A man pushes a cart with a constant force of 200 N at an angle 30° above the horizontal. If he does 750 J of work, how much distance is covered by the cart?

A one-dimensional force has the form F(x) = A x2-Bx where A =1.8 N/m2 and B = 0.65 N/m. How much work is done by the force in moving a 1.2 kg box from x = 0.78 m to x = 2.4 m? Enter your answer in Joules.

You pull a wagon across a floor with a force of 25 N over a distance of 30 meters.The handle of the wagon you are pulling on has an angle of 35 degrees above the horizontal.a) How much work do you do on the wagon?You now let your wagon roll down a frictionless slope from rest. The height of the slope is 5 meters, and the angle of the slope with the horizontal is 10 degrees. Assume the mass of the wagon is 10 kg.b) What is the final velocity of the suitcase (hint: use the work-energy theorem).

A weight lifter bench‑presses a 150.0 kg barbell from his chest to a height equal the length of his arms, 0.850 m. How much work does he do? How many food calories does the weight lifter use if he does this lift 35 times? Assume the weight lifter does no work in letting the barbell drop back to his chest.

The graph shows the x component of a force that acts on an object that moves on the x axis. The vertical spacing between adjacent grid lines is 4.98N, while the horizontal spacing between adjacent grid lines is 1.0m. What is the work, in joules, done by the force as the object moves from x = 4m to x = 5m ? F (N) C C 0 x (m)

You push a heavy box along the floor with a force of 775 N for a distance of 15 meters.  The friction force you push against is 255 N. How much work do you do (just you)?

a) A stationary bowler is getting ready to throw the bowling ball. She holds a 6.0 kg bowling ball 1.4 m above the ground for 2.0 s. How much work is done on the ball by the bowler? b) A pencil case is pushed eastward with a force of 11 N. Over what distance did the force act on the pencil case if it did 14 J of work on it?

A 10 kg barbell is rolling down a hill. There is no friction or air resistance acting on it, only the force of gravity. If it starts out moving 2 ms1, and ends up moving 7 ms1, then how much work does gravity do on it?

A shopper pushes a grocery cart for a distance 21.5 m at constant speed on level ground, against a 32.5 N frictional force. He pushes in a direction 26.5° below the horizontal. What is the work done on the cart by the gravitational force, in joules? What is the work done on the cart by the shopper, in joules?  Find the magnitude of the force, in newtons, that the shopper exerts on the cart. What is the total work done on the cart, in joules?

A warehouse worker pushes a crate across a rough floor. A frictional force of 22.5 N acts to oppose the motion of the crate, and the worker pushes with a horizontal force of 40.6 N. If the total work done by the worker on the crate is 98.0 J, through what distance did the worker push the crate?
