The angular displacement of a hoop travels in a circle is 4 rad, the radius of the hoop makes is 0.5m calculate the hoopsTangential displacement

Hi there!

We can relate linear displacement to angular displacement with the following;

d = tangential/linear displacement (m)

θ = angular displacement (rad)

r = radius (m)

Plug in the givens:

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.
