negative work.

17. We have seen man}.r examples offi'iction doing negative work. In this goblem we see fiiction doing
positive work to accelerate a car. A 1500 kg car accelerates uniformly from rest to 10 this in 3.0 s on a
level road. Neglect air resistance or other dissipative forces- a) b) C)
d) 6) Find the work done on the car in this time. What force does the work &
to accelerate the car? Find the average power delivered to the car over the 3 s. Does your answer underestimates or
overestimates the true power output of the engine? Explain Determine the instantaneous power delivered to the engine at 2 sec- Derive general expressions for the average power and for the instantaneous power for a car of
mass m that accelerates at rate a for atime I. By what factor would doubling the mass of the car, without changing the driving force, affect the
instantaneous power output?I
