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.

:)

c)as speed changes, wavelength and frequency change.

everything changes!
