Velocity-time curve for a body projected vertically upwards is

A

Parabola

B

Ellipse

C

Hyperbola

D

Straight line

Step-by-Step Solution

  1. Equation of Motion: A body projected vertically upwards moves under the influence of constant acceleration due to gravity (gg). The velocity (vv) at any time (tt) is given by the first equation of motion: v=ugtv = u - gt, where uu is the initial upward velocity .
  2. Linear Relationship: The equation v=ugtv = u - gt is a linear equation of the form y=mx+cy = mx + c, where the slope m=gm = -g (constant) and intercept c=uc = u.
  3. Graphical Representation: A linear relationship between velocity and time plots as a straight line on a graph. The negative slope indicates that velocity decreases uniformly as the body rises .
