A boat with a mass of 35000kg sails at 12 m/s on a heading of 80
degrees. A wind blowing along a compass heading of 305 degrees
exerts a force of 7000 N on the boat. An ocean current exerts
another force on the boat, this time of 10,500 N along a heading of
300 N. Calculate the force that the boat’s engine must produce for
the boat to maintain a constant speed.
