A car travels in a straight line at speed v along a horizontal road. the car moves against a resistive force f given by the equation F=400+kv2 where f is in Newton's, v in ms-1 and k is constant. At speed v=15ms-1,the resistive force f is 1100N calculate (i) the power necessary to maintain the speed of 15ms-1,(I)the total resistive force at a speed of 30ms-1, (I) the power required to maintain the speed of 30ms-1
