Hi there, I am a grade 11 student, learning physics. 1. The problem statement, all variables and given/known data A driver of a car going 90km/h suddenly sees the lights of a barrier 40.0 m ahead. It takes the driver 0.75s before he applies the brakes and the average accelleration during braking is -10.0m/s2. a) Determine whether or not the car hits tha barrier. b) What is the maximim speed at which the car could be moving and not hit the barrier at 40.0 m ahead? Assume the accelleration does not change. a) Treat toward the barrier as positive. v2=0m/s delta(t)= 40 v1=25m/s a=-10m/s2 I am not quite sure how to do b) 2. Relevant equations v2^2 = v1^2 + 2a(delta(d)) <---- a) 3. The attempt at a solution I have already determined that it would take the car 50 m to come to a complete stop, so it would hit the barrier. I am having trouble with b) thanks in advance.
