Question

A 8150 kg sailboat is moving through the waters of the Atlantic. Initially, the boat is traveling at 30 mph, 17 degrees East of North. After 12 minutes, the boat is travelng at 34 mph, 29 degrees West of North. Three forces are acting on the boat, Force due to resistance from the water: 9 N, 29 degrees S of W Force from an auxiliary motor: 7 N, 19 degrees E of N Force due to the wind: Fwind What is the net force (Fnet) acting on the boat? How many N how many degrees north of east? What is the force of the wind acting on the boat? How many N how many degrees N of E?

Explanation / Answer

follow this The horizontal net force without wind would be: Fnet = 7cos 29-9 sin29 and the acceletarion without wind would be: a = Fnet / mass =F/8150= 0.0246 m/s
