A student is driving at a constant 55.0 mi/hr (24.6 m/s) along a straight section of Route 3 North. The car directly ahead of him is
also moving at 55.0 mi/hr. The front bumper of the student's car is located 10.0 m from the rear bumper of the car ahead when,
at t=0, the driver of the car ahead applies his brakes and begins to slow down at a steady rate of
5.00
m/2. towards the posted "road construction" speed limit of 40.0 mi/hr (17.9 m/s). After slowing to 40.0 mi/hr, the driver
of the car ahead plans to maintain this constant speed. It takes the student 1.00 second to notice that the car ahead is slowing
down, and another 1.00 second to effectively apply his brakes and begin to slow down. Assume that, once the student
effectively applies the brakes, his car slows down at a steady rate of 5.00 m
At t=0, the student's front bumper is located at X = 0 and the car ahead begins to slow down at a steady 5.00m/s^2
