In a box car a helium filled balloon is tied to the, floor with a string. Car is moving on a horizontal road. If suddenly breaks are applied, what happens to the balloon. Will it jerked forward, backward or remain at rest.

A stone is tied with a string and is rotated in a circle horizontally. When the string suddenly breaks, the stone will move

When car is moving on a horizontal icy floor, if its brakes are locked,wheels stops rotating and starts liding. What happens to rotational kinetic energy ?

A simple pendulum is suspended from the ceiling of a car and its period of oscillation is T when the car is at rest. The car starts moving on a horizontal road with a constant acceleration g (equal to the acceleration due to gravity, in magnitude) in the forward direction. To keep the time period same, the length of th pendulum

Inside a railway car a plumb bob is suspended from the roof and a helium filled balloon is tied by a string to the floor of the car. When the railway car accelerates to the right then.

A motor cycle and a car are moving on a horizontal road with the same velocity. If they are brought to rest by the application of brakes, which provided equal retarding forces, then

One end of light inelastic string is tied to a helium filled ballloon and its other end is tied bottom of a water filled container at point O. The container lies on a fixed horizontal acceleration of magnitude a. Assuming no relative motion of balloon and water with respect to container, the string will be inclined with vertical line passing through O by an angle (h is acceleration due to gravity)

A car is moving with a uniform speed on a level road. Inside the car there is a balloon filled with helium and attached to a piece of string tied to the floor. The string is observed to be vertical. The car now takes a left turn maintaining the speed on the level road. The balloon in the car will

A simple pendulum of length l is suspended from the ceilling of a car moving with a speed v on a circular horizontal road of radius r. a. Find the tension in the string when it is at rest with respect to the car. b.Find the time period of small oscillation.
