Aboat moves through the water with two forces acting on it. one is a 1500 n forward push by the water on the propeller, and the other is an 1300 n resistive force due to the water around the bow.
(a) what is the acceleration of the 1200 kg boat?
(b) if it starts from rest, how far will it move in 7.0 s?
c) what will its velocity be at the end of that time?

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.
