**Marth**, Tuesday, June 30, 2009 at 10:14amFind the required acceleration.

a = (Vf-Vi)/t

where Vf = final velocity and Vi = initial velocity

You want final velocity to be 0.

a = (0-10)/5

a = -2 m/s/s

Now to find the force:

F = ma

F = 900*-2

F = -1800N

The force required is 1800N applied opposite from the direction of motion.
