A 95 kg rowboat is initially at rest, until it is pulled toward the dock with a rope with a tension of 30.0 N. The dock is higher than the boat, and the rope makes an angle of 25° at the place where it meets the boat. What is the acceleration of the boat?
Fn = ma,
a = Fn / m = 30cos25 / 95 = 0.29m/s^2.
