A duck has a mass of 2.0 kg. As the duck paddles, a force of 0.12 N acts on it in a direction due east. In addition, the current of the water exerts a force of 0.24 N in a direction of 47° south of east. When these forces begin to act, the velocity of the duck is 0.09 m/s in a direction due east. Find the magnitude and direction (relative to due east) of the displacement that the duck undergoes in 3.1 s while the forces are acting.
Problem 3: A toy duck is floating on the water. The average density of the duck is 880 kg/m3, while the density of water is g=1.0 x 10^(3) kg/m. The volume of the duck is Va=0.00011 m^(3)
Part (a) Express the weight of the duck, W, in terms of
Part (b) Calculate the numerical value of W in Newtons.
Part (c) Express the magnitude of the buoyant force, F. in terms of the volume of water that the duck displaces .
Part (d) Express the volume of the duck in water, Vw, in terms of e. Od and Vd
A river has a steady speed of 0.500 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. If the student can swim at a speed of 1.20 m/s in still water, how long does the trip take?
