JEE Main Physics question

A particle is thrown upwards, then the correct – graph will be

(A)A single straight line with constant negative slope, from at launch, through zero at the peak, to at landingCorrect
(B)A "V"-shaped (speed) graph, decreasing then increasing
(C)A symmetric "mountain" shape, rising then falling back to zero
(D)A horizontal (constant-velocity) line

Answer: (A)

As in Q106, constant acceleration throughout the flight makes a single straight
