A lake has still waters (no moving current). A boat on that lake can move at a speed of 7.5 km/h. If the boat is now moving on a stream that has flowing water, determine how fast the boat can move, relative to a tree on shore, when it travels (a) upstream and (b) downstream. Assume the stream has a speed of 3.2 km/h.
A boat takes 6 hours to go downstream and takes 8 hours to go the same distance upstream. The speed of the stream is 6 km/hr. Which of the following is true? Indicate all correct options. A. Speed of the boat upstream is 42 km/hr B. Speed of the boat downstream is 48 km/hr C. Distance travelled one way is 288 km D. Distance travelled one way is 28 km E. Speed of the boat in still water is 42...
A boat is traveling upstream at 11 km/h with respect to thewater of a river. The water is flowing at 6.0 km/h with respect tothe ground. (a) What is the speed of the boat with respect to theground? (b) A child on the boat walks from front to rear at 6.0km/h with respect to the boat. What is the child's speed withrespect to the ground?
Q17 A river is 0.76 km wide. The banks are straight and parallel. The current is 4.0 km/h and is parallel to the banks. A boat has a maximum speed of 4km/h in still water. The pilot of the boat wishes to go on a straight line from A to B, where the line AB is perpendicular to the banks. The pilot should a) head directly across the river b) head 53° upstream from the line AB c) head 37°...
A woman can row a boat at 6.00 km/h in still water. (a) If she is crossing a river where the current is 3.00 km/h, in what direction must her boat be headed if she wants to reach a point directly opposite her starting point? Express your answer as an angle with respect to the line perpendicular to the river, positive �f down the river. (b) If the river is 6.00 km wide, how long will she take to cross...
A small motorboat travelled downstream for 8 hours with a 1 km/h current to reach a campsite. The return trip against the same current took 9 hours. Find the speed of the motorboat in still water. Instructions: Enter your answer as a whole number, fraction or radical. When entering units, type without capitals, eg km/h, mph, feet, meters, yards, etc The speed of the motorboat in still water is Number Units
This Question: 1 pt 25 of 25 This Test: 25 pts possible In still water, a boat averages 7 miles per hour. It takes the same amount of time to travel 22 miles downstream, with the current as 6 miles upstream against the current.

QUESTION 4 Two planes A and Bare flying at the same altitude. If their velocities are = 500 km/h and 1700 km/h such that the angle between their straight-line courses is 8 = 60°, determine the velocity of plane B with respect to plane A. - 500 km/h - 700 km/h B The magnitude of the velocity of B with respect to A in km/h is QUESTION 5 The conveyor belt is moving downward at 4 m/s. If the ms...
QUESTION 2 A man can row a boat at 2 m/s in still water. He wishes to cross a 50-m-wide river to point B, 50 m downstream. If the river flows with a velocity of 2 m/s, determine the speed of the boat and the time needed to make the crossing 50 m 2 m/s A 50 m B T T T Arial 3 (12pt) • T ABC III
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...
