Police can estimate the speed of a vehicle before the brakes are applied using the formula 0.75d=(s^2)/(30.25) where s is the speed in miles per hour and d is the length of the vehicle’s skid marks. What was the approximate speed of a vehicle that left a skid mark measuring 150 feet
Accepted Solution
A:
150ft is 0.028 miles So (0.75x0.028)=(sxs) / 30.25 Meaning (0.75x0.028)x 30.25 = (sxs) And then square root to get the s
