Sam, whose mass is 72 kg, takes off across level snow on hisjet-powered skis. The skis have a thrust of 270 N and a coefficientof kinetic friction on snow of 0.15. Unfortunately, the skis runout of fuel after only 13s.
What is Sam's top speed?
How far has Sam traveled when he finally coasts to a stop?
Someone else gave me the wrong answer, please help!
