Answer 1

Answer:

Explanation:  The displacement of a particle moving in a straight line, is given by s = 2t^2 + 2t + 4 where s is in metres and t in seconds. The acceleration of the particle is. ... 2m/s2. 4m/s2. 6m/s2. 8m/s2. Answer : B. Solution : s=2t2+2t+4,a=d2sdt2=4m/s2. Related Videos. VIEW ALL · The displacement of a particle moving .
