A ship is sailing at 8 knots (nautical miles per hour) on a heading of 300. The wind is blowing at 12 knots from a bearing of 045. Find the speed (the magnitude of the resultant velocity) of the ship. find / (3) 1. If x)- 2 sin 3x, find f An airplane is flying at 150 km/h on a heading of 070. The wind is blowing at 40 km/h from a bearing of 130. Find the groundspeed (the magnitude of the ground velocity) of the airplane. A kayak is being paddled at 3 knots (nautical miles per hour) on a heading of 280. The current is flowing at 5 knots towards a bearing of 310. Find the speed (the magnitude of the resultant velocity) of the kayak. A father pulls a child in a sleigh with a 150 N force at an angle of 25 to the ground. How much work is done over a 2 km walk?
