In his Mustang, Juan rounds a curve onto a straight section of country road while traveling at a speed of 17.0 m/s , only to find a fully loaded manure spreader completely blocking the road a distance 38.0 m ahead of him. Startled, he travels at a constant velocity for a period of reaction time of 0.850 s , then hits the brakes and slows at constant acceleration so that he manages to stop just short of the spreader.
With the same reaction time and acceleration, if he had roared around the corner at a speed of 28.0 m/s instead of 17.0 m/s, how fast would he have been going when he hit the spreader?
How much time would he have had for his life to flash before his eyes from the time he first sees the spreader until he hits it?
