Answer:
Acceleration of the particle = 
Step-by-step explanation:
We are given the position vector of a particle moving in a circle of radius b units.
r(t) = b cos(ωt)i + b sin(ωt)j
Velocity , v =
= -bω sin(ωt)i + bω cos(ωt)j
The magnitude of velocity, v =
Squaring both sides,

Since
= 1

The acceleration towards the centre is called the centripetal acceleration and is given by
a = 
a = 
a = 
Radius, r = 7.2
Height, h = x
Surface of the cylinder
2*pi*r*x
Volume of the cylinder
pi*r^2*x
2*pi*r*h = pi*r^2*h
2 = r
