when the moving brakes are applied to a moving car travelling at 60km/h, it discelerates at a uniform rate at 5m/s. calculate the time taken to reach the velocity of 36km/hr.

Answer 1

Vo = 60km/h = 60,000m/3600s = 16.7 m/s.
V = 36km/h = 36,000m/3600s = 10 m/s.

V = Vo + a*t = 10.
16.7 + (-5)t = 10,
T =
