Q. A ball is thrown vertically upwards. Which of the following plots represents the speed-time graph of the ball during its flight if the air resistance is not ignored
A)
B)
C)
D)
Explanation
(c) For upward motion
Effective acceleration $= - (g + a)$
And for downward motion
Effective acceleration $= (g - a)$
But both are constants. So the slope of speed-time graph will be constant
