    Newton's Second Law
    I need help understanding how to solve this problem F=ma if:
    how much force is needed to acceleratea 1000-kg car at a rate of 3m/s-squared
    I don't understand the steps involved. Thanks for your help.

    I find it helps if I can "see" the event.

    hey, the equation given is very simple: the mass of the car is given which is 1000kg and the acceleration of the car is also given which is 3metre per second squared...

    so just multiply those two... F=ma =1000x3=3000N .

    The answer would be in Newtons.
