A 1500 kg caracceleratesuniformly from rest to a speed of 18m/s in 4.59 s.



A) Find the WORK done by the NET FORCE on the car during thistimeinterval. (Answer in units of J.)
acceleration=2.349 m/s^2
force=3570.69 N
distance=25.289 m
work=90300.91 J



B) Find the average power DELIVERED by the NET FORCE to the carinthis time interval. (Answer in units of w.)
power=19461.403 J/s


C) What is the instantaneous power delivered by the NET FORCE tothecar at 2 s? (Answer in units of w.)
i cant figure this one out! please explain it to me.
