A stone is dropped from the top of a tower of height 45 m. One second later another stone is thrown down from the town of the same tower. Both stones reach the ground at the same time. If (g= 10 m/s^2), magnitude of the initial velocity of the sound stone is

A stone is shot straight upward with a speed of 20 m/s from a tower 200 m high. The speed with which it strikes the ground is (g=10 m/s^2)

A stone is released from the top of a tower 90m high. At the same instant a second stone is projected vertically upwards from the ground with a velocity of 30 m//s . When and where will the two stones meet?

Solve the following examples / numerical problems: A stone is dropped from rest from the top of a building 44.1 m high. It takes 3 s to reach the ground . Use this information to calculate g.

A stone is thrown vertically upwards from the ground with a velocity 15 m/s. At the same instant a ball is dropped from a point directly above the stone from a height of 30 m. At what height from the ground will the stone and the ball meet and after how much time? (Use g= 10 m//s^2 for ease of calculation).

An engine driver moving towards a wall with a velocity of 60 m//s emits a note of 1400 Hz. Speed of sound in air is 340 m//s . The frequency of the note after reflection from the wall as heard by the engine driver is

A man drops a 20 kg object from the top of a 10m high building . What will be the velocity of the object when it just hits the ground?

Two stones are thrown up simultaneously from the edge of a clir 240 m high with initial speed of 10 m/s and 40 m/s respectively. Which of the following graphs best represents the time variation of relative position of the second stone with respect to the first? (Assume stones do not rebound after hitting the ground and neglect air resistance, take g=10 m/s^2 ) (The figures are schematic and not drawn to scale).

A man shouts loudly close to a high wall. He hears an echo. If the man is at 40 m from the wall, how long after the shout will the echo be heard? (speed of sound in air = 330 m//s )

The observer is moving with velocity 'v_0' towards the stationary source of sound and then after crossing moves away from the source with velocity ' v_0 '. Assume that the medium through which the sound waves travel is at rest, If 'v' is the velocity of sound and 'n' is the frequency emitted by the spurce then the difference between apparent frequencies heard by the observer is
