# A particle accelerates from rest at a constant rate for some time and attains a constant velocity of 8 ms^{-1}. Afterwards it decelerates with a constant rate and comes to rest. If the total time taken is 4 second, the distance travelled is:

A. 32 metre

B. 16 metre

C. 4 metre

D. insufficient data

Answer :

Now, from the given velocity – time graph we can calculate the distance by calculating area under the graph.

Distance Travelled = Area under the graph

=

= 16 m

Hence option B is correct
