Answer:
-6.0 m/s, 10.4 m/s
Explanation:
To find the x- and y- components, we have to apply the formulas:


where
v = 12.0 m/s is the magnitude of the vector
is the angle between the direction of the vector and the positive x-axis
Here, the angle given is the angle above the negative x-axis; this means that the angle with respect to the positive x-axis is

So, the two components are:


"watt" means "Joule of energy per second"
"60 watts" means "60 Joules per second"
(60 joules per second) x (5 seconds) = <em>300 Joules of energy</em>
I believe the answers you're looking for is effectively but not efficiently. The reason its these choices is because although you finished the job, it was not done in the best way possible. So it was effective, but not efficient.
