A ball placed on the ground seems to be at rest for us. Is it actually at rest? If not then why?

To determine whether the ball placed on the ground is actually at rest, we need to analyze the concept of rest and motion in relation to different frames of reference. Here’s a step-by-step solution: ### Step 1: Define Rest and Motion - **Rest**: An object is said to be at rest if it does not change its position with respect to a reference point. - **Motion**: An object is in motion if it changes its position with respect to a reference point. ### Step 2: Identify the Reference Frame - When observing the ball on the ground, we typically use the Earth as our reference frame. From this perspective, if the ball does not move, we say it is at rest. ...

A spherical rigid ball is realeased from rest and starts rolling down an inclined plane from height h=7m, as shown in the figure. It hits a block at rest on the horizontal plane (assme elastic collision). If the mass of both the ball and the block is m and the ball is rolling without sliding, then the speed of the block after collision is close to
