Question

A gnat takes off from one end of a pencil and flies around erratically for 41.641.6 s before landing on the other end of the same pencil. If the gnat flew a total distance of 6.656.65 m, and the pencil is 0.04630.0463 m long, find the gnat's average speed and the magnitude of the gnat's average velocity.

Answer 1

average speed is 0.159 m/s

average velocity = 0.0011 m/s

Step-by-step 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 =
`(total distance)/(total time)` ...............1

put here value

average speed =
`(6.65)/(41.6)`

average speed is 0.159 m/s

and

average velocity formula is

average velocity =
`(displacement)/(total time)` ...............2

here displacement is initial point to final point and here is 0.0463 m

put here value

average velocity =
`(0.0463)/(41.6)`

average velocity = 0.0011 m/s
