What force is required to accelerate a 950 kilogram car 20 kilometers per hour to 45 kilometers per hour in 7 seconds? How far does the car travel during its acceleration?

  • physics - ,

    change km/hr to m/s

    acceleration= change in velocity/time

    force= mass*a

    distance=Vi^t+1/2 a t^2 or an easier way
    distnace=avgvelocity*time where avg velocity =( intial+final)/2
