1. The problem statement, all variables and given/known data A speeding car has instantenous velocity of 1 m/s when a stopwatch reads 10 seconds. It has constant acceleration of 2 m/s^2. What is the cars speed when it reaches the stopwatch reads 12 seconds. 2. Relevant equations x= (Vinitial)(DeltaT) + 1/2(a09deltaT)^2 I think this is the right equation for constant acceleration... 3. The attempt at a solution (1.0m/s)(2seconds) + 1/2(2m/s/s)(2)^2 2 + 4 = 6 m/s This is a problem in my textbook, and the answer they give is 5 m/s. Am i using the wron equation? Or what am i doing wrong?
