How much work does the force you apply do on the car?
Homework Answers
we have the displacement vector
= (41*cos240)i + (41*sin240)j = -20.5i + -35.5j
work done =
= 
+ 
= -68*(-20.5) + 36*(-35.5) = 116 joules
so,the work done by the force = 116 joules

You have a rocket of mass 2350 kg. How much work does the force of gravity do on the rocket if it moves from Earth's surface to 3.0 times the Earth's radius away? Be careful to use the definition of work that accounts for a force that changes based on location!
