Answer:


Explanation:
Given that:
The radius of the table r = 16 cm = 0.16 m
The angular velocity = 45 rpm
= 
= 4.71 rad/s
However, the relative velocity of the bug with turntable is:
v = 3.5 cm/s = 0.035 m/s
Thus, the time taken to reach the bug to the end is:


t = 4.571s
So the angle made by the radius r with the horizontal during the time the bug gets to the end is:



Now, the velocity components of the bug with respect to the table is:





Also, for the vertical component of the velocity

Kinetic Energy,K.E=1/2MV²
mass,m=16kg
velocity,v=4m/s
K.E=1/2×16×4²
=128kgm²/s²
=128 Joules
