Homework Statement
A mass accelerates from 2.5ms^(-1) to 7.5ms^(-1) over a distance of 45m. Find the acceleration and the time it takes to do this.
Homework Equations
I know I need to use s=0.5(u+v)t
But I have no idea how to rearrange it to find t, I am useless at rearranging equations.
The Attempt at a Solution
I got t=0.5(u+v)-s
I know I did it wrong because I have the answer to the questions here, But It's not really what I'm looking for.
I need to know how to do it.
Any help would be appreciated.
Cheers,
Ben
