Homework Equations
a=d/t
xf=xi+vixt+1/2(a)t^2
Fnet=ma
The Attempt at a Solution
I know that to find out this problem I need to find out the Fnet. I know that Fnet=ma but how do I find out the a!?
I know to figure out acceleration its distance/time but..
How do I figure out acceleration? This is getting really frustrating. It gets to 90 mi/hr in 1.6m.
Does mass have anything to do with finding out the acceleration? Please help!
