Skylar pulls a 6.00-kg crate across a horizontal floor for a distance of 2.6 m as shown. The tension force in the rope is 93 N and the angle is 30.0° with respect to the horizontal. The frictional force on the crate is 19 N. What is the work done by the friction force, in Joules?

A tow truck pulls a car 4.30 kmkm along a horizontal roadway using a cable having a tension of 820 NN.   Part A- How much work does the cable do on the car if it pulls horizontally? Express your answer with the appropriate units.   Part B- How much work does the cable do on the car if it pulls at 37.0 degrees above the horizontal? Express your answer with the appropriate units.   Part C-How much work does the cable do on the tow truck if it pulls horizontally? Express your answer with the appropriate units.   Part D-How much work does the cable do on the tow truck if it pulls at 37.0 degrees above the horizontal?Express your answer with the appropriate units.   Part E-How much work does gravity do on the car in part A? Express your answer with the appropriate units.

Outside the space shuttle, you and a friend pull on two ropes to dock a satellite whose mass is 600 kg. The satellite is initially at position m and has a speed of 5 m/s. You exert a force N. When the satellite reaches the position m, its speed is 6.77 m/s. How much work did your friend do? Work done by friend =

A man pulls a 100-N crate up a frictionless 30° slope 5-m high, as shown. Assuming that the crate moves at a constant speed, the work done by the man is: a.  - 500  J b.  - 250 J c.  0 J d. + 250 J e. + 500 J
