Find the x-components of this vector: 15.3m, 65 degrees. Angles are measured from the +x axis.

x = 13.87m

Explanation:

Finding the x-components of this vector means that we resolve the vector into x component.

The angle to the x - axis is

90 - 65 = 25

Using trigonometry ratio,

X - component: cos 25 = x/15.3

Cross multiplication leads to

x = 15.3cos 25

x = 13.87m

the pull of gravity on the rocket decreases

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
