In our problem, the 80 m corresponds to the distance A, and so the average speed of 4 m/s (average speed in the direction straight across the river) should be substituted into the equation to determine the time. time = (80 m)/ (4 m/s) = 20 s. It requires 20 s for the boat to travel across the river.
The primary formula used to calculate the displacement of a ship is based on its physical dimensions and block coefficient. The block coefficient is a dimensionless number that describes how closely the shape of a ship resembles a rectangular block.
So let’s review and see if we can make sense of displacement in terms of numbers and equations. You can calculate an object's displacement by subtracting its original position, d 0 , from its final position d f .
The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page demonstrates the process with 20 sample problems and accompanying solutions.
The Riverboat Simulator Interactive allows a learner to investigate the effect of a river current, river width, and boat velocity upon the time to cross a river and the arrival location on the opposite bank.
Riverboat Problems. Example: Boat has velocity 5m/s with respect to the river. It aims to reach point A, however, because of the river speed it reaches another point B.
