Chapter 11, Problem 94A

To determine

To write:- The physics problem with real life object for which given equation will be the part of solution.

Explanation of Solution

Introduction:

Given problem is based on the work −energy theorem. It states that the, ‘amount of work done by the particle during a journey is equal to the change in its kinetic energy.’

Mathematically it can be represented as,

  $W=K.E_f-K.E_i$

Where,

  $K.E_f=$ Final kinetics energy.

  $K.E_i=$ Initial kinetics energy

  $W=$ Work done.

The physics problem with real life object for which given equation will be the part of solution. Can be written as follow:

Suppose wooden box of mass 6 kg dropped from height 0.92 m under the influence gravity. Calculate the speed at which box hit the ground?

Conclusion:

Hence, the problem has been written with the given information.
