A500. n box is placed on a frictionless inined plane that makes a 30.0 degree angle with the horizontal.
a) how fast would the box accelerate down the ramp?
b) how far down the ramp would it travel after 0.0850s?

answer:



be more realistic. the answer would be b for this question. i took this and it was b.

explanation:

the independent variable, or the one that is intentionally manipulated is the speed.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
