Draw a neat labelled diagram of conical pendulum. State the expression for its periodic time in terms of length.


Read the statement below carefully and state, with reason, if it is true or false:

The velocity vector of a particle at a point is always along the tangent to the path of the particle at that point.


A particle starts from the origin at t = 0 s with a velocity of 10.0 `hatj "m/s"` and moves in the x-y plane with a constant acceleration of `(8.0 hati + 2.0 hatj) ms^(-2)`.

  1. At what time is the x-coordinate of the particle 16 m? What is the y-coordinate of the particle at that time?
  2. What is the speed of the particle at the time?

A cyclist is riding with a speed of 27 km/h. As he approaches a circular turn on the road of radius 80 m, he applies brakes and reduces his speed at the constant rate of 0.50 m/s every second. What is the magnitude and direction of the net acceleration of the cyclist on the circular turn?


Is it possible to have an accelerated motion with a constant speed? Name such type of motion.


A particle is moving in uniform circular motion with speed 'V' and radius 'R'. The angular acceleration of the particle is ______.
