Calculating the push force on a vehicle

  1. Mar 18, 2010 #1

    I am trying to work out what force you would need to push a four wheel vehicle of mass 200kg from rest to a top speed of 2m/s (acceleration 1m/s2) and the force needed to maintain that top speed . I am not sure how to go about this, do i just consider rolling resistance and take that as 0.01...does static friction come in somewhere?

    Simple F=ma. If you want to account for friction, I don't know, .01 sounds like a good number.

    I wouldn't worry about static friction. The force needed to accelerate as fast as you want is MUCH greater than the static friction, and the static friction can only hold you back before you even start accelerating....
