Next >

An object is subjected to three constant forces: F₁ = 6.0 N east, F₂ = 8.0 N south, and F₃ = 6.0 N west. If these forces act on the object for 2.0 seconds, what is the total impulse delivered to the object?

A

16 N·s south

B

8√2 N·s southeast

C

16 N·s north

D

Zero, because the horizontal forces cancel
