SUMMARY

A swimmer with a speed of 1.15 m/s in still water aims to cross a 150 m wide river with a current of 0.80 m/s. The swimmer's motion consists of two components: one across the river and one downstream due to the current. To determine how far downstream she lands, one must calculate the time taken to cross the river and then use that time to find the distance carried downstream by the current. The swimmer will take approximately 130 seconds to cross, resulting in a downstream displacement of 104 meters.

PREREQUISITES
  • Understanding of vector addition in physics
  • Basic knowledge of kinematics
  • Familiarity with the concept of relative motion
  • Ability to perform calculations involving speed, distance, and time
NEXT STEPS
  • Study vector addition in two-dimensional motion
  • Learn about relative velocity in fluid dynamics
  • Explore kinematic equations for projectile motion
  • Investigate the effects of currents on swimming techniques
USEFUL FOR

Students studying physics, swimming coaches analyzing swimmer performance, and anyone interested in the effects of currents on aquatic movement.

A swimmer is capable of swimming 1.15 m/s in still water.
(a) If she aims her body directly across a 150 m wide river whose current is 0.80 m/s, how far downstream (from a point opposite her starting point) will she land?
:cry: I have tried this twice and I have gotten the wrong answer does anyone know how I am supposed to do this?
 
Physics news on Phys.org
The swimmer's motion will have 2 components, one across the river and one downsteam (carried by the current). The resulting motion will be the vector addition of the 2 components.
 
The nice thing about the "components" hotvette mentioned is that you can work with them completely separately.

If there were no current at all, how long would it take this swimmer to cross the river?

Now include the current- in the time you just calculated, how far downstream will the current carry her?
