A skater of mass m = 60 kg is coasting along a smooth, level road with initial velocity v = 3 m/s East. A sudden gust of wind exerts a time-varying force on him given by: F(t) = (30 N) (1 - t) where t is measured in seconds. The gust of wind lasts from t = 0.0 to t = 2.0 seconds. What is the skater's speed at 2.0 seconds?
