Physics Motion in a Straight Line JEE Main

A ball is thrown vertically upwards. Which of the following graph/graphs represent velocity-time graph of the ball during its flight (air resistance is neglected)

(A)A "V"-shaped graph (velocity decreasing then increasing, with a kink)
(B)A "Λ"-shaped graph (velocity increasing then decreasing, with a kink)
(C)A "V"-shaped graph through the origin
(D)A single straight line, continuously decreasing from through zero to Correct

Answer: (D)

Solution

The acceleration is the constant throughout both the rise and fall, so
