What is the distance traveled?

Expert Solution

Step 1

Given Data:

The mass of a ball is, $m = 20 kg$

The speed of a ball is, $v = 4.5 m/s$

The coefficient of kinetic friction is, $μ_{k} = 0.23$

By using work-energy theorem,

$\begin{array}{rcl} W & = & K \cdot E \\ Fricitonal force (f_{f}) \cdot d & = & \frac{1}{2} m v^{2} \\ μ_{k} m g \cdot d & = & \frac{1}{2} m v^{2} . . . . . . . . . . . . . . . . . . (1) \end{array}$

Here, m is the mass, g is the acceleration due to gravity and v is the speed.
