Question

What is the stone’s velocity after 1 second?
m/s

Answer 1

Answer:

we know that ,

$velocity = \frac{displacement}{time} \\ \\ velocity = \frac{2m}{1s} \: = \: 2 \: m \: s {}^{ - 1}$

hope helpful~

Answer 2

v = d : t

d = distance/position

t = time

from the graph for t = 1 s, d = 3 m, so the velocity of the stone:

v = 3 : 1 = 3 m/s
