When brakes applied to a moving car travelling at 60km/hr it decelerates at a uniform rate of 5ms-2. Calculate the time taken to reach a velocity of 36km/hr
Convert the two km/h speeds to m/s.
60 km/h = 16.67 m/s
36 km/h = 10.00 m/s
Deceleration time requred
= (16.67 - 10)/a = ___ seconds
is a is in units of m/s^2
K=F/e
