Word problem on braking distance

Trigonometry: D = 1.05 (V1^2 - V2^2)/64.4(K1 + K2 + sin θ) K1 is a constant determined by the efficiency of the brakes and tires, K2 is a constant determined by the rolling resistance of the automobile, and θ is the grade of the highway. a. Compute the number of feet required to slow a car from 55 mph to 30 m ...continues
