Chapter 6.1, Problem 1E

To determine

To calculate:To find the position of the particle at t=4.

Answer to Problem 1E

The position of the particle at t=4 is x=20.

Explanation of Solution

Given information,

  $\begin{array}{l}x=0\\ v\left(t\right)=5 ,t\ge 0\\ \text{To find}x\text{at }t=4.\\ \text{We know that},\\ x=v\times t\dots \dots \dots \dots \left(i\right)\\ at,t=4,\\ \text{putting the value of }t=4\text{ and }v=5\text{ in}\text{the}\text{equation}(i)\text{ we get},\\ x=5\times 4\\ x=20\\ \text{So,the particle in at }x=20\text{ when }t=4.\end{array}$
