Question

Which of the following curves represent the v- t graph of an object a falling on a metallic surface

and bouncing back?​

Answer 1

Explanation:

Representing Free Fall by Position-Time Graphs

As learned earlier, a curved line on a position versus time graph signifies an accelerated motion. Since a free-falling object is undergoing an acceleration (g = 9.8 m/s/s), it would be expected that its position-time graph would be curved.
