The motion of a skateboard along a horizontal axis is observed for 5 s. The initial position of the skateboard is negative with respect to a chosen origin, and its velocity throughout the 5 s is also negative. At the end of the observation time, the skateboard closer to or farther from the origin than initially? Explain.

Hence, the board will be farther away from the origin than initially.

Explanation:

We are given a situation, in which a skate board is in motion for 5 seconds. It is stated that initially the skate board is in negative side of the origin and its velocity during the 5 seconds is also negative. We are required to determine whether the skate board will be farther or closer to the origin at the end of the motion.

Lets assume that the left side of the origin is negative while the right side is positive. So, the skate board is at the left side of origin initially. Since, its velocity is negative, it means the board is moving more towards the left side. Hence, the board will be farther away from the origin than initially.

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic
