a) Sam's top speed can be calculated using the equation v = (F/μm)t, where F is the thrust, μ is the coefficient of kinetic friction, m is the mass, and t is the time. Plugging in the given values, we get v = (220N/0.1*80kg) * 8.0s = 176 m/s.
b) The distance traveled can be calculated using the equation d = vt, where v is the velocity and t is the time. Plugging in the given values, we get d = 176 m/s * 8.0s = 1408 m.
Sam, whose mass is 80kg , takes off across level snow on his jet-powered skis. The skis have a thrust of 220N and a coefficient of kinetic friction on snow of 0.1. Unfortunately, the skis run out of fuel after only 8.0s.
a) What is Sam's top speed?
b) How far has Sam traveled when he finally coasts to a stop?
