A 9650 kg sailboat is moving through the waters of the Atlantic. Initially, the boat is traveling at 13 mph, 21 degrees East of North. After 5 minutes, the boat is travelng at 16 mph, 10 degrees West of North. Three forces are acting on the boat, Force due to resistance from the water: 14 N, 24 degrees S of W Force from an auxiliary motor: 9 N, 20 degrees E of N Force due to the wind: Fwind What is the net force (Fnet) acting on the boat? ? N ?degrees N of E What is the force of the wind (Fwind) on the boat? ? N ?degrees N of E Will rate for clear working!
