An 1520 kg car is moving to the right at a constant velocity of 2.94 m/s.

    An 1520 kg car is moving to the right at a constant velocity of 2.94 m/s.

    (a) What is the net force on the car?
    (b) What would be the net force on the car if it were moving to the left?

    any help i tried using Force=Mass*Acceleration
    I also dont know what it wants me to dod when it asks when it moves to the left?

    A constant velocity means that no acceleration exists. If no acceleration exists, then the sum of the forces must be zero (in both cases). Doesn't matter what direction the car is going; if it isn't accelerating, then the net force is 0.

    Oh it was that easy. I was kinda thinking to hard

    Thanks BishopUser
