Question 45

A tram is tested twice using the same constant resultant braking force. In the second test it carries more passengers, so its mass is 1.25 times its mass in the first test, and it brakes from 1.6 times its speed in the first test. Its braking distance in the second test is 96.0 m. What was its braking distance in the first test?
