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!!
