Question

You walk in a straight line for 95 m at an angle of 162° above the positive x axis. What are the x and y components of your displacement?

Answer 1

Answer:

Explanation:

{ r, θ ) = [ r cosθ i , r sinθ j ]

( 95m , 162°) = [ 95 cos 162 i, 95 sin 162 j]

( 95m , 162°) = [ 95 * -0.951 i, 95 * 0.309 j]

( 95m , 162°) = -90.342 i, 29.355 j =

[ -90.34 m i , 29.36 m j ]

Therefore, the displacement of x and u components are

x displacement = -90.35 m and y displacement = 29.36 m

round appropriately
