starting form rest a cars moves with unifrom acceleration and attians a velocity of `20 ms^(-1) and 4 s`. It then moves what a unifrom velocity of `20 ms^(-1)` for 6s. The brakes are applied and the car is brought to rest in 10s under unifrom retardation . Draw the velocity group for the motion. using theis graph , find (i) the acceleration of the car during the frist 4 s (ii) ua retardation during the last 10 s and (iii) the total distance traveled by the car . |
