a=f/m



all that i have down is the forula but there is no other variables.

Use the constant acceleration motion equations. If you don't know them google motion equations

wow they are really confusing

is there a way i can get the solution without trying to figure them out???


how can i find the force if i dont even know the acceleration?

wait.... i have this nifty little equation you can use to calculate the acceleration with the final velocity..... d=(vi)(t)+(1/2)(a)(t)^2 vi is the initial velocity, and that equals zero, so you can cut that out and use the d=(1/2)(a)(t)^2 and work the equation to equal a.... that is all i am gonna give you
