Question: A car traveling at 120km/h strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.85m.
Question 1: What was the magnitude of the average acceleration of the driver during the collision?
I need help to solve the above question and express the answer in terms of "g's," where 1.00 g = 9.80 m/s2. And express your answer using two significant figures.
