The oil tanker has a smooth surface area of $4.5 \times 10^3 m^2$ in contact with the sea. The velocity of the ship is 2 m/s. Suppose that L = 350 m. Take $\rho = 1030 kg/m^3$ and $\mu = 1.14 \times 10^{-3} N \cdot s/m^2$. Determine the friction drag on its hull. Express your answer to three significant figures and include the appropriate units. Determine the power required to overcome this force. Express your answer to three significant figures and include the appropriate units.

Question # 1: A motorist drives south at 20.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.00 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.00-min trip, if the positive x-axis points east, find: a) the total vector displacement b) the average speed c) the average velocity Question # 2: A particle initially located at the origin has an acceleration of 3.00j m/s$^2$ and an initial velocity of 5.00i m/s. Find: a) the vector position of the particle at any time b) the velocity of the particle at any time c) the coordinates of the particle at $t$ = 2.00 s d) the speed of the particle at $t$ = 2.00 s Question # 3: Two forces, (-6i-4j) N and (-3i+7j) N, act on a particle of mass 2.00 kg that is initially at rest at coordinates (22.00 m, 14.00 m). a) What are the components of the particle's velocity at $t$ = 10.0 s? b) In what direction is the particle moving at $t$ = 10.0 s? c) What displacement does the particle undergo during the first 10.0 s? d) What are the coordinates of the particle at $t$ = 10.0 s?
