# Velocity-time graphs of two objects P and Q are as given below:

(i) Which object starts from rest?

(ii)Which object has more velocity after 5 s?

Answer :

(i) The object in Graph Q starts from rest as when time is zero, velocity is also zero.

(ii) Graph P will have more velocity after 5 secs as from the graphs we can infer that in Graph P after 5 secs the velocity is 14 m/s whereas in Graph Q the velocity reaches 12 m/s. Both the graph shows uniform acceleration but object in graph P has an initial velocity of 2 m/s and object in graph Q starts from rest.
