What is the force required to accelerate it from rest to 1.5 m/s in 2.5 seconds?

**bobpursley**, Saturday, October 11, 2008 at 8:09amYou know the pushing force for constant velocity, so the horizontal component of the pushing force must be friction. Find that.

Now

Forcenet=forcefriction+ Mass*acceleration.

Solve for the net force, knowing mass, acceleration, and the force of friction.
