1. The problem statement, all variables and given/known data A car is initial at rest. It accelerates over a distance of 1250m and reaches a speed of 112 km/h. Find: A) the acceleration for the car B) the time it took for it to reach this final speed C) the average speed 2. Relevant equations A = delta V/ delta T or v^2 = V (initial)^2 + 2a (d -d(initial)) d = d(initial) + vt 3. The attempt at a solution 1250 = 0 + 31.1(t) t = 40.18 A = 31.1/40.18 A = .77 m/s^2 BUT here is the problem if i use v^2 = V (initial)^2 + 2a (d -d(initial)) 31.1^2 = 0^2 + 2a(1250) A = .387 m/s^2 that is half of the first one? that is where i need help Thanks!
