JEE Main Physics question

Physics Motion in a Straight Line JEE Main

Acceleration-time graph of a body is shown (two separated positive rectangular pulses with a zero-acceleration gap between them). The corresponding velocity-time graph of the same body is [DPMT 2004]

(A)A trapezoidal shape (rise, flat top, decline)
(B)A zigzag (rise, dip, rise again)
(C)A ramp that rises, holds flat partway, then continues rising at a steeper or shallower angleCorrect
(D)A ramp that rises, then declines partway, then rises again

Answer: (C)

Solution

With acceleration positive, then zero, then positive again, velocity rises linearly, then stays
