(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The toy car has been placed on an inclied ramp facing downward. angles are as follows 10degrees , 12 degrees , 14 degrees , 16degrees , 18 degrees, 20 degrees.

after acceleratin down the ramp for 15cm, the car continues on a leveled plane.

between which consecutive angles will show a big difference in their speed and distance traveled.

2. Relevant equations

Fnet = ma

Fgx - Ff = ma

vf ^2 = vi ^2 + 2ad

3. The attempt at a solution

my prediction is that there will be biggere difference in 12 and 14 degree angles because the

car hasnt put to its full potential yet and at low angles like this one, it is easier to see the performance increase.

or would it be the other way around 16 degree angle and 18 degree angle?

i know that as the angles increase the x-component of the gravitational force increases more than the frictional force which is the reason why the car travels further and further.

can someone please help with this concept Help !
