A swimmer heads directly across a river, swimming at her maximum speed of 1.60 m/s relative to the water. She arrives at a point 40.0 m downstream from the point directly across the river, 67.0 m wide. In what direction (as an angle relative to a direct line across the river) should the swimmer aim instead, so that she arrives at the point directly opposite her starting point?
1)A canoeist paddles directly across a river at 5 m/s. At the same time, the river is pushing the canoeist sideways at 3 m/s. What is the angle of the canoe's motion relative to the riverbank? 2)A molecule in the air has a mass of 2 x 10-25 kg. At a temperature of 25ºC, how fast is it moving?
If a boat points its prow directly across a river, and its engine has one speed of 8 57 m/s What is its speed, relative to the river bank, if the river has a velocity of 3.22 mis? Number Units If the river is 52.9 m wide, how far down stream does it land when it reaches the opposite shore? Number Units
A 70 m wide river flows from north to south at a speed of 3.2 m/s. A swimmer swims relative to the water at a rate of 4.6 m/s aiming across the river at an angle of 24 degrees north of east. What is the speed of the swimmer with respect to the shore? How far downstream (south), from a point directly across the river, does the swimmer hit the shore?
Looking for help on#4 A swimmer heading directly across a river 200 m wide reaches the opposite bank in 6 min 40 s, during which time she is swept downstream 480 m. How fast can she swim in still water? What is the speed of the current?
A 0.20-km wide river has a uniform flow speed of 4.054 m/s toward the east. A boat with a speed of 80 m/s relative to the water leaves the south bank and heads in such a way that it crosses to a point directly north of its departure point. How long does it take the boat to cross the river? 29s 23s 25s 27s 17s
A Swimmer speed in still water is 1.85m/s. If the boat is traveling north directly across a river whose westward current has a speed of 1.2m/s at what upstream angle must the boat head?
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...
a boat is heading due east across a river with a velocity of 7.0 m/s with the respect of water. The current of the water is flowing south with a velocity of 3.0 m/s. What is the speed and direction of the boat with respect to an observer on the bank of the river?
Huck Finn walks at a speed of 0.70 m/s across his raft (that is, he walks perpendicular to the raft’s motion relative to the shore). The raft is traveling down the Mississippi River at a speed of 1.50 m/s relative to the river bank (Fig. 3–42). What is Huck’s velocity (speed and direction) relative to the river bank?
