What is q1?
Show answer
A 5050 N force pulls a crate 8.08.0 m along the floor at 3030^\circ above the horizontal. Calculate the work done by the force. [2 points]
What is q2?
Show answer
A force-position graph is a straight line from F=10F = 10 N at x=0x = 0 to F=0F = 0 at x=4.0x = 4.0 m. Calculate the work done over this interval. [2 points]
