Sam, whose mass is 80 kgkg , takes off across level snow on his jet-powered skis. The skis have a thrust of 160 NN and a coefficient of kinetic friction on snow of 0.10.1. Unfortunately, the skis run out of fuel after only 15 ss .   What is Sam's top speed? Express your answer to two significant figures and include the appropriate units.   How far has Sam traveled when he finally coasts to a stop? Express your answer to two significant figures and include the appropriate units.
