Questions & Step-by-Step Solutions
A swimmer can swim at 3 km/h in still water. If the current of the river is 2 km/h, what is the swimmer's speed relative to the bank when swimming upstream?
Relative Speed – Understanding how to calculate the effective speed of an object in a moving medium, such as a swimmer in a river.
Vector Addition – Applying the concept of vector addition to determine the resultant speed when two velocities are acting in opposite directions.
