Boat A is rescuing boat B, which is stranded at sea, by pulling it back to shore. Boat A is driven by a propeller, whereas boat B is floating freely. When connected by a rope, and starting from rest, the speed of A increases uniformly to 36 km/h in 32 seconds. Determine: (a) The force in the rope (b) The force provided by the propeller of boat A to move it forward Neglect friction with the water. m = 50,000 kg B 00 O A O mA = 30,000 kg Boat A is rescuing boat B, which is stranded at sea, by pulling it back to shore.
