A particle is moving in a straight line. The particle was initially at rest. Acceleration versus time graph is shown in the figure. Acceleration of particle is given by \[a=3\text{ }sin\,\,\pi t\]in\[m/{{s}^{2}}\]. The time instant (s) when the particle comes to rest is
A)\[t=0,1,2,3,4\]
B)\[t=1,3\]
C)\[t=0,2,4\]
D)only at \[t=0\]
Correct Answer:
C
Solution :
[c] Area under the a-t curve gives change in velocity.
