Physics Motion in a Straight Line JEE Main

A stone is released from a balloon moving upwards with velocity at a height at . Which of the following graphs is the best representation of the velocity–time graph for the motion of the stone?

(A)A single straight line, starting at at and declining with constant slope , crossing through zero and continuing into negative valuesCorrect
(B)A "V"-shaped graph (speed graph)
(C)A horizontal (constant-velocity) line
(D)A curve concave-down, flattening out

Answer: (A)

Solution

The stone shares the balloon's upward velocity at release, then undergoes constant
