Initially, the car travels along a straight road with a speed of 35m/s. If the brakes are applied and the speed of the car is reduced to 10m/s in 15 s, determine the constant deceleration of the car.

Expert Answer:

intial velocity, u = 35 m/s
final speed, v = 10m/s
time taken, t  = 10 sec
acceleration = rate of change of velocity = (v-u)/t  = -2.5m/s2
