Question
Velocity-time graphs of two objects P and Q are as given below:
Which object has more velocity after 5s?
✓

Answer

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