A car accelerates from rest at a constant rate of 2ms−2 for sometime. Then, it retards at a constant rate of 4ms−2 and comes to rest. If the total time for which it remains in motion is 3s, what is the total distance travelled?

Question : A car accelerates from rest at a constant rate of 2ms−2 for sometime. Then, it retards at a constant rate of 4ms−2 and comes to rest. If the total time for which it remains in motion is 3s, what is the total distance travelled?

(A) 2m

(B) 3m

(D) 6m

Answer : option (D)

Solution :
