A seconds pendulum is suspended from the roof of a lift. If the lift is moving up with an acceleration 9.8 m/s2 its time period is

The time period of a simple pendulum inside a stationary lift is T. If the lift starts. moving upwards with an acceleration of g/3 what will be its time period ?

A simple pendulum is suspended from the roof of a lift. What will be its time period when the lift moves downwards with an acceleration a

How is the period of a pendulum affected when its point of suspension is moved horizontally with acceleration a.

An object dropped from a cliff falls with a constant acceleration of 10 m/s2. Find its speed 5 s after it was dropped.

A boy standing on a stationary lift (open from above) throws a ball upwards with the maximum initial speed he can, equal to 49 m/s. How much time does the bail take to return to his hands? If the lift starts moving up with a uniform speed of 5 m/s and the boy again throws the ball up with the maximum speed he can, how long does the ball take to return to his hands?

Find the force required to move a train of mass 5000 quintals up an incline of 1 in 50 with an acceleration 2ms^-2 . Take force of friciton = .2N/s qunital and g = 10ms^-2 .

How is the period of a pendulum affected when its point of suspension is (a) moved vertically upwards with acceleration a.

If a body starts from rest and travels 1.2 m in 8th second , then acceleration is

A monkey of mass 40 kg climbs on a rope (Fig. 5.20) which can stand a maximum tension of 600 N. In which of the following cases will the rope break: the monkey (a) climbs up with an acceleration of 6 m s^2 (b) climbs down with an acceleration of 4 m s^2 (c) climbs up with a uniform speed of 5 m s^1 (d) falls down the rope nearly freely under gravity? (Ignore the mass of the rope).

How is the period of a pendulum affected when its point of suspension is moved vertically downward with a acceleration a < g.
