If a ball rolls down an inclined plane and picks up 4 m/s each second it rolls, its acceleration is
To find the acceleration of the ball rolling down an inclined plane, we can use the formula:
acceleration = change in velocity / time
In this case, the ball picks up 4 m/s of velocity each second it rolls. Therefore, the change in velocity is 4 m/s, and the time interval is 1 second. Plugging these values into the formula:
acceleration = 4 m/s / 1 second = 4 m/s²
So, the acceleration of the ball rolling down the inclined plane is 4 m/s².
