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
1) 2 m/s2
2) 4 m/s2
3) 6 m/s2
​

Answer 1

Explanation:

The displacement of a particle moving in a straight line, is given by s=2t2+2t+4 where s is in metres and t in seconds. The acceleration of the particle is. Solution : s=2t2+2t+4,a=d2sdt2=4m/s2
