A disk (radius, r = 5 m, mass, m = 50 kg) is resting on a perfectly frictionless surface. Two students, Morrigan and Samael, are standing at the outer edge, opposite from each other. Both Morrigan and Samael have masses, mh, = 50 kg (they are both at r = 5 m). At exactly the same time, both Morrigan and Samael start walking counter-clockwise at v = 1 m/s relative to the disk. What is the angular speed of the disk?

i don’t know what the answer is i wish i

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.
