QUESTION 1: Suppose a boat moves at 18.8 m/s relative to the water. If the boat is in a river with the current directed east at 3.10 m/s,what is the boat's speed relative to the ground when it is heading east, with the current, and west, against the current? (Enter your answers in m/s.) HINT (a) east with the current m/s (b) west against the current m/s QUESTION 2: An airplane maintains a speed of 663 km/h relative to the...

EXERCISE HINTS: GETTING STARTED I I'M STUCK! A pipe carrying water from a tank 19.5 m tall must cross 3.15 x 102 km of wilderness to reach a remote town. Find the radius of the pipe so that the volume flow rate is at least 0.0500 m3/s. (Use the viscosity of water at 20°C, 1.0 x 10-3 N·s/m?) 3 Check units and do not follow the example too closely. You will need to solve for the desired unknown. There is...
