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 $5$secs as from the graphs we can infer that in Graph $P$ after $5$secs 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.
