Goals: SWBAT...

1. Determine the components of vectors

WARM-UP & HW CHECK (10 min)

Josue weighs 640N, and sits in a grocery cart on the slope of a hill that descends at an angle of 35.0* from the horizontal. What are the components of his weight parallel and perpendicular to the surface of the hill.

a: draw your axes

b. draw an FBD

c. Solve for Fgx and Fgy
