Answer:
The disk will reach the bottom first.
Explanation:
As we know:
change in kinetic energy = change in potential energy
ΔK.E = -ΔP.E
For the disk:
For Hoop:
Hence
Velocity for the disk:
Velocity for the Hoop:
Hi there!
Recall the equation for centripetal force;
m = mass (kg)
v = velocity (m/s)
r = radius (m)
We are not given the mass directly, we are given the object's weight.
Now, we can plug this value along with the given velocity and radius to solve:
