A 61.0 kg box is sitting at rest. In order to change the box's state of motion, Jamie must apply 75.1 Newtons of force on the box.
1. Which of the following represents a posarble value for the force of static friction when
Jamie applied 75.1 Newtons of force on the box?
A. 71.9 N
B. 75.1 N
C. 85.3 N
D. 133 N
2. How much magnitude of force does the box exert back on Jamie's hand?
A. 4400 N
B. 1.20 N
C. 75.1 N
D. 0.00 N

a, c, d, e are all applying about success strategies.

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

hope that                                         : )
