The moment arm of the shoulder abductor muscles is approxi- mately 5 cm from the axis of rotation of the shoulder joint, and the force vector representing shoulder abductor muscle force is oriented at approximately 150° relative to the positive x-axis. the weight of the upper extremity of an 80-kg male is approximately 45 n. if the person is 1.78 m in height, then the center of gravity of the upper-extremity is approximately 0.25 m from the shoulder joint.
3. calculate the vertical component of the joint reaction force.
4. calculate the horizontal component of the joint reaction force.
5. calculate the orientation of the vector representing joint reaction force.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

given values:

mass = 0.3 kg.

the ima (higher than 1m) will be greater than the ima with the height of 1m.
