Concept explainers

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

**Problem Statement:**

Sam, whose mass is 71 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 240 N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skis run out of fuel after only 15 seconds.

**Part A:**

*Question:*
What is Sam's top speed?

*Answer:*
\( v = 36 \, \text{m/s} \)

*Feedback:*
Correct

**Part B:**

*Question:*
How far has Sam traveled when he finally coasts to a stop?

*Prompt:*
Express your answer with the appropriate units.

*Answer Box:*
\( s = \)
[Submit Button]

**Additional Information:**

- The coefficient of kinetic friction affects the net force acting against Sam's motion.
- The skis provide a thrust that propels Sam until the fuel runs out after 15 seconds.
- You need to consider the forces involved to determine Sam's top speed and how far he travels before stopping.

Please use this information to solve Part B and express your answer in meters.
