In \(1.0\) s, a particle goes from point A to point B, moving in a semicircle of radius \(1.0\) m (see figure). The magnitude of the average velocity is:

A stone tied to the end of a string of \(1\) m long is whirled in a horizontal circle with a constant speed. If the stone makes \(22\) revolutions in \(44\) s, what is the magnitude and direction of acceleration of the stone?
 

If the equation for the displacement of a particle moving on a circular path is given by \(\theta = 2t^3 + 0.5\) where θ is in radians and t in seconds, then the angular velocity of the particle after 2 sec from its start is:

1. 8 rad/sec

2. 12 rad/sec

3. 24 rad/sec

4. 36 rad/sec

For a particle in a non-uniform accelerated circular motion

(2) Velocity is transverse and acceleration is radial only

(3) Velocity is radial and acceleration has both radial and transverse components

(4) Velocity is transverse and acceleration has both radial and transverse components

The coordinates of a moving particle at any time ‘t’ are given by x = αt³ and y = βt³. The speed of the particle at time ‘t’ is given by:

3. $3$ $t^2\sqrt{{\alpha }^2+{\beta }^2}$

4. $t^2\sqrt{{\alpha }^2+{\beta }^2}$

The figure shows a body of mass m moving with a uniform speed v along a circle of radius r. The change in velocity in going from A to B is:

(4) zero

A particle moves in a circular path with decreasing speed. Choose the correct statement. 

(1) Angular momentum remains constant
