u = a/g = 0.8
a = 0.8*g = 0.8 * (-9.8) = -7.84 m/s^2
d = (V^2-Vo^2)/2a = (0-(20^2)/-15.68 =
25.5 m. To stop.
75-25.5 = 49.5 m. from deer.
You are driving down a highway at a speed of 20.0m/s when you spot a deer. You quickly slam on your brakes, trying to stop your car in front of the deer. Assume the braking force can be modeled as kinetic friction with a friction coefficient of 0.80. If the deer was 75.0m away from you when you slam on your brakes, will you hit the deer? If you do, find the speed at which you hit it. If you don't, find how far from the deer you stop
