Energy that is lost as heat -is destroyed -is absorbed by other objects -can still be used to do work

Energy that is lost as heat is still absorbed by other objects. 

Energy cannot be created nor destroyed. This is according to the law of conservation of energy. It is transformed into one form to another. So this means the first option is not the answer. Energy that is lost as heat is less able to be used for work. This is due to entropy, so the last one is not the answer. 

The car would move to the right with 150 n of force. the 150 n of force from friction and air resistance slows the car from moving to the right with 300 n of force.
