is there more to this? if so i would love to help you!!
The rubber band has elastic potential energy
Answer:
The easiest way to tackle this problem is by breaking the vectors up into their components (also it's easier to type this method).
G = 40.3 cos (-35.0°) i + 40.3 sin (-35.0°) j ----where i denotes the x direction and j denotes the y direction
H = 63.3 sin (270°) j ----- I left off the i component because i know cos 270 is 0.
40.3 and 63.3 are the magnitudes of your vector, or the hypotenuse of a triangle. We are finding the horizontal (Adjacent) and vertical (Opposite) legs the respective hypotenuse (we have to remember SOH COH TOA)
Now you can simply add components
G + H = (40.3 cos (-35.0)) i + (40.3 sin (-35.0°)+ 63.3 sin (270)) j ----be sure to pay close attention to signs when doing your calculations on your calculator.

Calculating the Power:
Given:
Answer:
The speed of this particle is constantly .
Explanation:
Position vector of this particle at time :
.
Write as a column vector to distinguish between the components:
.
Both and are constants. Therefore, and would also be constants with respect to . Hence, and .
Differentiate (component-wise) with respect to time to find the velocity vector of this particle at time :
.
The speed (a scalar) of a particle is the magnitude of its velocity :
.
Therefore, the speed of this particle is constantly (a constant.)
