Answer :

i) The value of angular momentum is 0.5


ii) The value of kinetic energy is 75 J


Given


Mass of the plate is given as 2kg and length of the sides of the square is 10cm with a torque of 0.10Nm.


Formula used


The of the average velocity is the basic kinematic equation of velocity, where



and



where


is the angular speed, I is the moment of inertia and K.E. is the kinetic energy is the average acceleration.


Explanation


(a) To find the average momentum which is



We need to find the values of







Then the value of kinetic energy is given as
