The force-displacement graph of a crate that was 45.0 pushed horizontally is shown at right. Refer to the graph to answer questions 16-21. 40.0 16. How far did the crate move horizontally? 35.0 30.0 25.0 17. What was the magnitude of the force that acted on the crate? 20.0 15.0 10.0 18. What does the area under the graph represent? 5.0 0.0 0.10 0.20 0.30 0.40 0.50 0.60 0.70 Displacement (m) 19. How much work was done in moving the crate 0.10 m? 20. Suppose you wanted to know the amount of work done in moving the crate 0.40 m. First, find the amount of work done using the graph. Then use the equation for calculating work to find the amount of work. How do your answers compare? 21. On the force-displacement graph above, draw a line that shows that the force uniformly increases from 30.0 N to 40.0 N as the crate is pushed from 0.50 m to 0.70 m. What is the total amount of work done on the crate as it moves from 0.0 m to 0.70 m
