1. Two forces act on a box as follows: F= 100 N at 02 = 170. and F2= 75 N at O2 = 30. Find their resultant force on the box.
(a) the magnitude of vector sum Fi + F
(b) the direction of of the vector sum F1+F2​

yfv.

Explanation:

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
