A toy car of mass `2 m` is at rest on a smooth horizontal surface. A small bob of mass m is suspended by a mass less string of length L from the roof of the car. A horizontally flying bullet of mass m enters into the car through a small window and sticks to the bob. Speed of the bullet is u. Find minimum value of u (call it `u_(0)`) for which the bob can touch the roof of the car

A simple pendulum with a bob of mass m is suspended from the roof of a car moving with a horizontal accelertion a. The angle made by the string with verical is

A toy car of mass m is placed on a smooth horizontal surface. A particle of mass 3m is suspended inside the car with the help of a string of length l . Initially everything is at rest. A sudden horizontal impulse I = 2m sqrt(gl) is applied on the car and it starts moving. (a) Find the maximum angle q_(0) that the string will make with the vertical subsequently. (b) Find tension in the string when it makes angle theta_(0) with the vertical.

A car is moving with constant speed of 10m/s on a horizontal circular path of radius 10sqrt(3m) . A bob of mass m suspended through a light string from the roof of the car. What is the angle made by the string with the vertical if the bob is stationary with respect to the car? (g = 10 m/ s^(2) )
