Please Help... A robot travels at a speed of 1.35 m/sec at a direction of 45.0 degrees for 305 seconds. It then travels at a speed of 1.50 m/sec at a direction of 140.0 degrees for 852 seconds. What is the total displacement at the end of the second maneuver? First, give the y component of the first displacement vector calculated in the problem.
|dw:1353046766024:dw|
|dw:1353046901075:dw| use cosine rule to find x
Don't I need to find the degrees of the other angles?
Does the cosine rule solve for both x and the angles?
A solution using Mathematica 8 Home Edition for the calculations and a plot is attached.
