In 1970, Don "Big Daddy" Garlits set what was then the world record for drag racing. He started at rest and accelerated at 16.5 m/s2 (about 1.68 times the free-fall acceleration) for 6.5 s. What was Garlits's final speed? *

107.3 m/s

Explanation:

The motion of Garlit is a uniformly accelerated motion (=constant acceleration), therefore we can use the following suvat equation:

where

u is the initial velocity

v is the final velocity

a is the acceleration

t is the time

In this problem, we have:

u = 0 (Garlit starts from rest)

is the acceleration

Therefore, the final velocity after t = 6.5 s is:

d) physical means can be used to separate the components of air.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
