Question

how long does it take a skateboarder going 6.0 m/s to come to a complete stop if she slows down at a rate of 2.0 m/s^2

Answer 1

Use the formula: v=v0+at

v is the final velocity

v0 is the initial velocity

a is the acceleration

t is the time

Plug in and solve for t:

0=6+(-2)t

*Subtract 6 from both sides*

-6=-2t

*Divide both sides by -2*

3 seconds=t

Hope this helps!!

Answer 2

It takes 3 seconds to a complete stop.

Use the following formula: v = v0+ at

v is the final velocity

v0 is the initial velocity

4a is the acceleration

t is the time

Put the above values:-

0 = 6 + (-2) t

* Subtract 6 from both sides *

444- 6 = -2t

* Divide both sides by -2 *

t= 3 seconds

What is Acceleration?

Acceleration is the change in velocity divided by the time period during which the change occurs. Since the SI unit of velocity is m / s and the SI unit of time is 's', the SI unit of acceleration is m / s2. The average acceleration is given by

a¯ = ΔvΔt = vf-v0tf-t0.
