Swimmer in a River: RELATIVE AND ABSOLUTE MOTION NUMERICAL PROBLEMS
A swimmer is crossing a river that flows at 2 m/s. The swimmer’s speed relative to the water is 4 m/s.
Determine the swimmer’s speed relative to the riverbank (absolute motion) when swimming directly downstream.
Determine the swimmer’s speed relative to the riverbank when swimming directly upstream.
A Boat is moving downstream on a river. Determine the speed of the boat relative to the riverbank (RELATIVE AND ABSOLUTE MOTION NUMERICAL PROBLEMS)
A boat is moving downstream on a river. The river flows at a speed of 3 m/s relative to the riverbank. The boat’s engine propels it at a speed of 7 m/s relative to the water.
Determine the speed of the boat relative to the riverbank (absolute motion).
If the boat turns around and starts moving upstream, what will be its speed relative to the riverbank?
Drive, Walk, Refuel: Find Displacement, Time & Velocity
You drive a car on a straight road at a constant speed of 70 km/h for a distance of 8.4 km, after which the car runs out of fuel. You then walk a further distance of 2 km for 30 minutes to reach the gas station. a) What is the total displacement from the beginning of your drive to your arrival at the gas station? b) What is the total time interval from the beginning of your drive to your arrival at the gas station? c) What is the average velocity from the beginning of your drive to your arrival at the gas station?
