Assuming that we have to calculate the time required for the car to come at rest.
v equals u plus a t 0 equals 7 minus 2.5 t t equals 7 divided by 2.5 t equals 2.8 m s to the power of negative 2 end exponent

Starting from rest, an object is uniformly accelerated to a speed of 60m/s in 20s. The object travels with this speed for next 40s and is then brought to rest by a uniform retardation in the next 30s.Sketch velocity time graph and calculate the acceleration, retardation and the total distance travelled. Hint: acceleration =rate of change of velocity.  distance covered =area under velocity-time graph .
