From the top of a water one particular is projected with velocity I in the horizontal direction and the other is dropped from rest. Do they reach the ground at the same time ?

From the top of a cliff 73.5 m a body is projected with a velocity of 19.6 m/s at an angle of 30^@ with the horizontal. Determine the time of flight, the distance from the foot of the tower and velocity with which the body strike the ground. g =9.8 m/ s^2

A stone is dropped from the top of a tower of height h. After 1 second, another stone is dropped from the balcony 20m below the top . Both reach the button simultaneously . What is the value of h ?

A particle is projected with velocity 2 sqrt((gh)) so that it just clears two walls of equal height h which are at a distance of 2h from each other. Prove that the time of flight between two walls is 2 sqrt((h/g))

A projectile is fired horyzontally with a velocity of 98 ms^(-1) from the top of a hill 490 m high.find the time taken to reach the ground.

How do trees draw water from ground?

A stone is allowed to fall from the top of a tower 300 meters high and at the same time another is projected vertically upwards with a velocity of 7.5 meter/sec. Find when and where the two stones meet?
