A hoop and a disk have the same mass and radius. The disk has half the moment of inertia of the hoop. If they start from rest at the top of a ramp, and if the reference for potential energy is at the bottom, which has the greater total energy?

when it gains or loses electrons

a=d/t

a="triangle"v/t

explanation:

a = acceleration

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
