Chapter 11, Problem 93A

To determine

To Write:A problem in which given bar diagram would be the part of solution.

Answer to Problem 93A

The problem can be, “A car running with constant velocity climbs on a hill without accelerating. Draw the bar diagram of kinetic and potential of car initially and midway through the climbing.”

Explanation of Solution

Introduction:

Kinetic Energy: This is the gained energy by an object because of its motion.

  $KE=\frac{1}{2}m{v}^2$

Here, $m$ is the mass and $v$ is the velocity of the object.

Potential energy:

It is the gained energy by the object due to increase in its height. It is given by the following equation,

  $PE=mgh$

Here, $m$ is the mass , $g$ is gravitational acceleration and $h$ is height gained by object.

The given bar diagram is,

For the above diagram, the question would be, “A car running with constant velocity climbs on a hill without accelerating. Draw the bar diagram of kinetic and potential of car initially and midway through the climbing.”
