Chapter 10: Q.41 (page 258)

A very slippery ice cube slides in a vertical plane around the inside of a smooth, $20 - c m$ -diameter horizontal pipe. The ice cube’s speed at the bottom of the circle is $3.0 m / s$ . What is the ice cube’s speed at the top?

Short Answer

Expert verified

Ice cube's speed at the top will be zero.

Step by step solution

Speed :

It is the change in an object's location with regard to time.

Explanation :

A highly slippery ice cube moves vertically across the inside of a smooth horizontal pipe with a diameter of $20 c m$ . At the bottom of the circle, the ice cube's speed is $3.0 m / s$ .

Ice cube's total energy $K E + P E$ remains constant $\frac{1}{2} m v^{2} + m g h = c o n s \tan t$ ,

$v$ = ice cube's velocity,

$- h$ = height from the bottom of the vertical circle.

The frictional force does no work since the pipe is smooth. When an ice cube is released from rest from a point on the vertical circle, it will reach the release height at the same speed as when it was released. As a result, the top ice cube's speed will be zero.
