Question

The speed of a falling object increases at a constant rate as time increases since the object was dropped. Which graph

could represent the relationship between t time in seconds, and s, speed in meters per second?

Answer 1

Explanation:

As the object is falling from a fixed Distance, so Speed increases as time increases.

Both speed and time are Directly proportional to each other if distance remains constant.

S = k T

When , T=0, S=0

T=1 s, S=1 m/s

T=2 s, S= 2 m/s

\frac{dS}{dT}=k=Change in speed(Average Speed), if it is Change in Velocity then it will be equal to =a (Acceleration).
