Aforce acts on a 5kg object at rest. how fast will the object accelerate on a frictionless surface?
a.) 4 m/s^2
b.) 15 m/s^2
c.) 25 m/s^2
d.) 100 m/s^2

The answer is C.) 25 m/s^2.

Explanation: If you input 5 as s, you would have to use the exponent 2.  This means that you have to multiply 5 by 5.  5 x 5= 25.  

Edit: Also, because the surface is frictionless, it will make the object go faster too.  Nothing can really slow it down unless something blocks it.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."
