 As a final thought, what do you think would happen if we doubled the steepness of the ramp, so as at 70 degrees instead of 35 degrees? You might think that since one of the numbers has doubled, the force would double, but that's actually not the case. We need to substitute the new value into the equation we derived to see the effect. Putting this in, we find that the net force is equal to mg times the sine of 70 degrees, which is 553 Newtons. As before, we can use our equation for acceleration to find that the experimentalist will accelerate at 9.2 meters per second squared. While this is bigger, it's not twice as big as our previous answer. The reason it's not twice as big is because when theta doubles, sine of theta doesn't double. In other words, sine isn't a linear function.
