Part C
Based on the vector diagram in Part B, determine how far downstream of your starting point you will finally reach the opposite shore if the stream is 6.0
meters wide.
▾ View Available Hint(s)
Hint 1. Find the time to cross the stream
Notice that your velocity has been given in component form: 3.0 m/s across the stream and 4.0 m/s along the stream. Based on these velocity
components, how long will it take you to cross the 6.0 meter wide stream?

A. From the perspective of point x, vector a and vector b are approaching with around the same speed. From Joseph's perspective, the two are walking with around the same speed. Determine if vector a is approaching with the same speed, twice the speed, or half the speed from the perspective of vector b. Explain.B. Vectors x and y are moving with uniform velocities. If the image below is t = 0, how long will it take (in seconds) for vector x to be in the same position with vector y? How far should vector x have traveled (in meters) by the time it has overtaken the position of vector y? Show proper solution.
Demonstration 1: Sketch on the axes on the right your
predictions for the x coordinate of the ball as a function of
time and the y coordinate of the ball as a function of time.
Based on your graph of x vs. t, write a kinematic equation
for x as a function of time.

equation for y as a function of time.
