Vector Composition & Decomposition

3. Vectors / Vector Composition & Decomposition / Problem 1

A ski jumper has an acceleration of magnitude 8.00 m/s² just before he leaves the ramp. The ramp makes an angle of 18.0° counterclockwise with respect to the horizontal. Calculate the a_x and a_y components of the skier's acceleration before he leaves the ramp.

A

a_x = 0 m/s²
a_y = -9.81 m/s²

B

a_x = 2.47 m/s²
a_y = 7.60 m/s²

C

a_x = 2.60 m/s²
a_y = 2.47 m/s²

D

a_x = 7.60 m/s²
a_y = 2.47 m/s²
