An olympic cross-country skier, Samantha Snodgrass, who has a mass is 75 kg, takes off across level snow under rocket power. The rocket has a thrust of 200 N and her skis have a coefficient of kinetic friction on snow of 0.1 . Unfortunately, the rocket runs out of fuel after only 10 seconds. What is Samantha's top speed? How far has Samantha traveled when she finally coasts to a stop?
