select the correct answer.\nin the absence of friction, gravity, and all other external forces, what kind of speed will an object display if it travels from the bottom to the top of an inclined plane?\na. constant speed\nb. increasing speed\nc. decreasing speed\nd. speed increases and then decreases\ne. speed decreases and then increases
Answer
Answer:
A. constant speed
Explanation:
Step1: Recall Newton's first law
An object in motion will stay in motion with a constant velocity in the absence of external forces.
Step2: Analyze the given situation
There are no friction, gravity or other external forces on the object moving on the inclined - plane. So, its speed remains constant.
