Question
A ball is vertically upwards. Which of the following plots represents the speed-time graph of the ball during its flight if the air resistance is ignored?
Options
A.
B.
C.
D.
Solution
For a body going in upward direction v = u - gt
The slope of the graph,
= - g (constant)
But when we take into account the effect of resistance it will have sharper slope.
Curve(d)fits into this result.
