Work Practice problems
Practice Problems Using the Work formula [W = (F)(d)(cosθ)], solve ONLY 5 of the next problems. Remember to include your procedure and the units!Each problem is worth 20 points, 10 of procedure and 10 of correct answer.Consider that each day of late delivery after the due date the classwork is worth 10 points less in its totality, with a limit of 7 days tardy assignment. Problems Results Procedure If 2 J of work is done in raising an apple with 180 N, how far is it lifted? 1.1 m A tugboat pulls a ship with a horizontal force of 500 N and causes the ship to move through a harbor. How much work is done on the ship of it moves a distance of 3,000 m? 15,000,000 J A weightlifter lifts a set of weights a vertical distance of 2 m. If a constant net force of 350 N is exerted on the weights, what is the work done? 700 J A shopper in a supermarket pushes a cart with a force of 35 N directed at an angle of 25°. Find the work done by the shopper on the cart as they move 50 m. 1,600 J A worker pushes a crate with a force if 345 N a distance of 24 m. How much work is done? 8,280 J You raise a ball 1.32 m above the ground with a force of .35 N, what is the work done on the ball? 0.462 J How much work is done on a vacuum cleaner pulled 3 m by a force of 50 N at an angle of 30° above the horizontal? 120 J A person lifts a cement block a vertical distance of 1.2 m applying a force of 45 N. Determine the work. 54 J A box of clothes is pulled 20 m with a force of 80 N up a 30° ramp. Calculate the work. 1,385.64 J A block slides 2.5 m down a rough 30° incline with a force of 50 N, what is the work done? 108.25 J A skier is pulled up a slope by a motor-driven cable. How much force is required to pull the skier 60 m up a 35° slope if the work is 800 J? 16.28 N A suitcase slides down a ramp inclined at 30° from the floor. If the work done is 63 J and the force applied is 5 N, how long is the ramp? 14.55 m An acrobat flies off at a 45° angle, moving 50 m doing a work of 275 J. What is the force he applied? 7.78 N A skier goes down a hill inclined 10.5°. He does a work of 740 J with a force of 26, what is the hillside longitude? 28.9 m A projectile is shot horizontally with a force of 144 N, performing a work of 17,615 J. What is the displacement of the projectile? 122.33 m If you wanna include the free body diagrams, you can do it here.
