A 135kg merry-go-round is initially at rest, when a student holding the rail begins
to run, generating the normal force shown for 1.7s. The equation for the
moment of inertia of any disk (such as a merry-go-round, neglecting the hand
rails) is I = 1/2mr.
Answer all questions relative to the center of the merry-go-round.
How much torque does she generate?
377 Nm
What is the moment of inertia?
114
kg m^2
What is the angular acceleration?
unit
What is the final angular speed?
rad/s
rpm

none, its a machine

momentum of soft ball three times less than baskey ball

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
