Sam, whose mass is 86 kg, takes off across level snow on hisjet-powered skis. The skis have a thrust of 230 N and a coefficientof kinetic friction on snow of 0.15. Unfortunately, the skis runout of fuel after only 11s.
What is Sam's top speed?
How far has Sam traveled when he finally coasts to a stop?
Please show method by which you solved this, which formulas wereused, etc.
