Sam, whose mass is 75 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 200 N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skis run out of fuel after only 10 s. What is Sam's top speed? (in meters/second)How far has Sam traveled when he finally coasts to a stop? (in meters)

Solution Summary

Answers question on impulse.

Solution Preview

Mass=m= 75 Kg
g= 9.81 m/s^2
Force from jet powered skis= 200 N
coefficient of kinetic friction on snow =Mu = 0.1
Friction force=Mu mg= 73.575 N =0.1x75x9.81

Therefore Net force acting on Sam= 126.425 N =200-73.575

Time for which the net force ...
