1. The problem statement, all variables and given/known data He decelerates uniformly at a rate of -5.00m/s^2 over from a velocity of 7.5m/s to rest. Find the time and displacement. 2. Relevant equations Vf^2=Vo^2 + 2a(displacement) 3. The attempt at a solution 0=56.25+2(-5)x is this the right way to find displacement? Solving for the x? For time would it be 0 = 7.5 + (-5)(t) which is 1.5? That doesn't really seem correct I'm confused.
