1) Among many alternative units that might be considered as a measure of time is the shake rather than the second. Based on the expression "faster than a shake of a lamb's tail," we'll define 1 shake as equal to 2.5 x 10^-4 s.
If a car is traveling at 50 mi/h, what is its speed in cm/shake?

highway.
The acceleration of gravity is 9.8 m/s^2 .
If the coefficient of friction between road
and tires on a rainy day is 0.09, what is the
minimum distance in which the car will stop?
(1 mi = 1.609km)
