You drop a stone from rest into a well that is `7.35 m` deep. How long does it take before you the splash ?

A stone is dropped into a well in which water is 78.4m deep. After how long will the sound of splash be heard at the top ? Take velocity of sound in air =332ms^(-1) .

A truck starts from the speed from rest with an acceleration 1.5m/s^2 while a car 150m behind starts from rest with an acceleration of 2m/s^2 . How long will it take before both the truck and car side by side and how much distance is travelled by each ?

A truck starts from rest with an acceleration of 1.5 m//s^(2) car 150 m behind starts from rest with an acceleration of 2 m//s^(2) . How long will it take before both the truck and car side byside, and how much distance is traveled by each?

A particle is dropped from a tower 180 m high. How long does it take to reach the ground ? What is the velocity when it touches the ground ? Take g=10m//s^(2) .

A stone is dropped into a well. The splash is heard 3.35 s later. What is the depth of the well?

A stone is dropped in a well which is 19.6 m deep. Echo sound is heard after 2.06 sec (after dropping) then the velocity of sound is

While standing on a bridge 15.0 m above the ground, you drop a stone from rest. When the stone has fallen 3.20 m, you throw a second stone straight down. What initial velocity must you give the second stone if they are both to reach the ground at the same instant ? Take the downward direction to be the negative direction .

A stone is dropped from the top of a tower 500 m high into a pond of water at the base of the tower. When is the splash heard at the top ? Given g = 10 m s^(-2) and speed of sound = 340 m s^(-1) .

A stone is dropped from the top of a tower 500 m high into a pond of water at the base of the tower. When is the splash heard at the top ? Given, g = 10 m//s^2 and speed of sound = 340 m//s .
