Homework Statement


(a) A car with a mass of 850kg is moving to the right with a constant
speed of 1.44 m/s . What is the total force on the car? (b) What is the total
force on the car if it is moving to the left?


Homework Equations


F=ma


The Attempt at a Solution


(a)F = 850kg(1.44m/s) = 1.22 x 10 third power
(b) is the same

Does this seem right?
Thanks,
Kevin

Note the constant speed. If there is constant speed, there is no acceleration. Therefore:

F_net must equal zero.

F=ma

You don't plug in velocity for the acceleration in that equation.
