Answer:
average speed is 0.159 m/s
average velocity = 0.0011 m/s
Explanation:
given data
time = 41.6 s
total distance = 6.65 m
length = 0.0463 m
to find out
average speed and the magnitude average velocity
solution
we know average speed formula is
average speed = ...............1
put here value
average speed =
average speed is 0.159 m/s
and
average velocity formula is
average velocity = ...............2
here displacement is initial point to final point and here is 0.0463 m
put here value
average velocity =
average velocity = 0.0011 m/s
