The pendulum in a clock is `14 ~cm` long. It moves through `40^(circ)` makes one oscillation. What is the distance travelled by the tip of the pendulum during one oscillation?

A car is moving along the circumferance of a circle of radius r . a)What is the distance travelled in one revolution? b)What is the displacement in one revolution? c)What does the speedometer of the car measure? d)Can a body have acceleration without velocity.Explain.

A bob of mass 0.1 kg hung from the ceiling of a room by a string 2 m long is set into oscilation. The speed of the bob at its mean position is 1 ms^(-1) . What is the trajectory of the bob if the string is cut when the bob is (a) at one of its extreme positions, (b) at its mean position.

A simple pendulum is an object suspended by a weightless and inextensible string fixed rigidly to a support. The period of oscillation of the pendulum is T. What will be the period if the pendulum is suspended in a lift moving down with an acceleration equal to g/3 .
