A car is traveling in a race. The car went from the initial velocity of 35 m/s to the final velocity of 6 m/s in 5 seco
is the acceleration?

-13 m/s?
-6 m/s
6 m/s
13 m/s

Explanation:

Acceleration =  a change in velocity / a change in time

Acceleration = ( final velocity - initial velocity) / a change in time

Acceleration = (6m/s - 35 m/s ) / 5 s

                     = (-29 m/s) /( 5 s)

                     = - 5.8 m/s^^2  

Remember Significant Figures  

- 6 m/s^2

P.S I have no idea why the answers say m/s because acceleration is m/s^2.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
