A river has a steady speed of 0.450 m/s. A student swims upstream a distance of 1.70 km and swims back to the starting point. If the student can swim at a speed of 1.40 m/s in still water, how long does the trip take swimming up and down in the current)? If the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.)
Q2 1. Kinematics of swimming A swimmer swims directly across a river of width L that flows with a constant and uniform speed uo. (a) If the swimmer swims with constant speed to. how long does it take them to cross the river? (b) How far downstream of their starting point does the swim- mer reach the opposite shore? (c) What is the minimum speed to that will allow the swimmer to cross the river? 2. Kinematics of swimming The...
2. Alice and Bob are swimming in a river. They start together at the same point on the bank of a wide stream that flows with a speed v. Both move at the same speed c where c> v) relative to the water. Alice swims downstream a distance L and then upstream the same distance. Bob swims so that his motion relative to the Earth is perpendicular to the banks of the stream. He swims the distance L and then...
An athlete crosses a 24.2 m wide river by swimming perpendicular to the water current at a speed of 0.4 m/s relative to the water. He reaches the opposite side at a distance of 45.3 m downstream from his starting point. How fast is the water in the river flowing with respect to the ground?
An athlete crosses a 21 m wide river by swimming perpendicular to the water current at a speed of 0.35 m/s relative to the water. He reaches the opposite side at a distance 38 m downstream from his starting point. a) How fast is the water in the river flowing with respect to the ground in m/s? b) What is the speed of the swimmer with respect to a friend at rest on the ground in m/s?
An athlete crosses a 31.9 m wide river by swimming perpendicular to the water current at a speed of 0.3 m/s relative to the water. He reaches the opposite side at a distance of 27.7 m downstream from his starting point. What is the speed of the swimmer with respect to a friend at rest on the ground?
2. Alice and Bob are swimming in a river. They start together at the same point on the bank of a wide strcam that flows with a speed v. Both move at the same speed c (where c > v) relative to the water. Alice swims downstream a distance L and then upstream the same distance. Bob swims so that his motion relative to the Earth is perpendicular to the banks of the stream. He swims the distance L and...

A river has a steady speed of 0.500 m/s. A student swims upstream a distance of 2.00 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?
A river flows from west to east with a speed of 3m/s. A boy swims north across the river with a speed of 2m/s relative to the water. (a) What is the speed of the boy relative to the shore? (b) What is the boys direction relative to the shore?
