Solutions

Chapter 2.6, Problem 40E
To determine

To find:The velocity and the speed of a moving particle along a straight line.

Expert Solution

Answer to Problem 40E

The velocity and the speed of a moving particle is 26/25 and 26/25 respectively.

Explanation of Solution

Given: A particle moves along a straight line where time is 5 second and the equation is

  f(t)=t1t

Given f(t)=t1t be any function.

The velocity is the first derivative of the position function which it found using the power rule.

  v(t)=f'(t)=t21plugging in 5 for tv(5)=f'(t)=1/251=26/25

Speed is the absolute value of velocity

  s(5)=|v(5)|=26/25

Hence, the velocity and the speed of a moving particle is 26/25 and 26/25 respectively.
