Question

Given below are four curves discribing variation of velocity with time of a particle.which one of these describe the motion of a particle initially in positive direction with constant negative acceleration ​

Answer 1

Answer:

∙ Constant acceleration (negative).

⟹ Velocity will decrease with time.

Graph (x) is eliminated.

∙ Constant acceleration.

⟹ Slope of v−t graph will remain constant.

Graph (w) eliminated.

∙ Given that initially the particle is in positive direction. Graph (z) eliminated.

Graph (y) satisfies all the above conditions.
