Chapter 4, Problem 85A

To determine

ToWrite: A physics problem with real object for the given equation.

Explanation of Solution

Introduction:

In the given equation,two values of physical quantities are given.

From the units provided the two physical quantities are

1. Mass $=23\text{ kg}$
2. Acceleration $=1.8{\text{ m/s}}^{\text{2}}$

And from these two values, force is to be calculated.

This equation is related to Newton's second law of motionas per which that rate of change of momentum is directly related to applied force.

  $F=ma$

The problem can be like this,

“A boy pushes the cart of mass $23\text{ kg}$ such that it accelerates at a rate of $1.8{\text{ m/s}}^{\text{2}}$

Find the force with which boy pushes a cart.”
