That gives you the direction relative to the bank. The question wants the direction relative to the water, which means you have to do vector addition.evo13 said:
Neither. Your fundamental problem is that ##c## is from the river's frame of reference and ##a## is from the banks frame of reference. You are mixing vectors from two reference frames in one diagram.evo13 said:
You do understand the question. You're trying a clever shorcut that doesn't work!evo13 said:
A velocity vector addition problem is a mathematical problem that involves adding or combining two or more velocity vectors to determine the resulting velocity.
To solve a velocity vector addition problem, you need to break down each velocity vector into its horizontal and vertical components. Then, add the horizontal components together and the vertical components together. Finally, use the Pythagorean theorem to find the magnitude and the inverse tangent function to find the direction of the resulting velocity vector.
Velocity vector addition problems are commonly used in physics and engineering to calculate the resulting velocity of an object that is moving in multiple directions. They are also used in navigation and aeronautics to determine the velocity and direction of an aircraft or spacecraft.
Yes, velocity vector addition problems can have negative solutions. This occurs when the resulting velocity vector is in the opposite direction of the initial velocity vectors. Negative solutions are common in physics and can represent deceleration or a change in direction.
Some common mistakes to avoid when solving velocity vector addition problems include forgetting to break down the velocity vectors into their components, using the wrong trigonometric functions to find the magnitude and direction, and forgetting to account for negative solutions. It is also important to pay attention to units and make sure they are consistent throughout the problem.
