Question

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
1) 2 m/s2
2) 4 m/s2
3) 6 m/s2
4) 8 m/s2​

Answer 1

Answer:

8m/s2

2m/s2

Explanation:

moving in a

Answer 2

Answer:

S=2t2+2t+4,a=d2s/dt2=4 m/s2
