A body falling freely under gravity passes two points 30 m apart in 1 s. From what point above the upper point it began to fall? (Take g = `9.8 m s^(-2)`).

A body falling freely under the action of gravity passes 2 points 9 m apart vertically in 0.2 s. From what height above the higher point did it start to fall?

A body is falling freely under gravity. It passes two points A and B (A being higher than B) 20m apart vertically in 2s. Find the elevation of the point above A from where it began to fall.

A ball is thrown up with a speed of 15 m//s . how high will it go before it begins to fall ? Take g=9.8 m//s^(2) .

A body of masss 1kg is allowed to fall freely under gravity. Find the mimimum and kinetic energy of the body 5 second after it starts falling. Take g= 10 ms^(-2)

A body falling freely on a planet covers 18 m in 3 s. What is the time period of a simple pendulum of length 1 m on the planet ?

A bullet of mass 20g is found to pass two points 30m apart in 4 s? Assuming the speed to be constant, find its kinetic energy?

A ball is thrown up with a speed of 15 m/s . How high wiil it go before it begins to fall ? (g=9.8 m//s^(2)

Find the horizontal velocity of the particle when it reach the point Q. Assume the block to be frictionless. Take g=9.8 m//s^(2) .

An aeroplane is flying in a horizontal direction with a velocity of 900 km/h and at a height of 1960m. When it is vertically above the point A on the ground, a body is dropped from it. The body strikes the ground at point B. The distance AB will be (take g = 9.8 m//s ^(2))
