Work = change in Kinetic Energy
(units are Joules)
KE = (1/2)*m*v^2
m = mass in kg
v = velocity in m/s
Power = work/time
(units are Watts)
a 2200kg car accelerates from 5m/s to 17m/s in 3 seconds.
a) find the work done on the car in this time period.
b)find the average power delivered by the engine in this time interval.
