[SOLVED] kinenatics (NOT cst acceleration) I have no idea how to solve a problem that doesn't have constant acceleration. I'm guessing you have to set up an equation using the given values and solve for the variable..but I don't know. This is the question anyhow: You're driving down the highway late one night at 15.5 m/s when a deer steps onto the road 51.2 m in front of you. Your reaction time before stepping on the brakes is 0.810 s, and the maximum deceleration of your car is 8.11 m/s^2. How much distance is between you and the deer when you come to a stop?
