h' A stone dropped freely from a height reaches the earth in 5 seconds. 'h' Calculate...

balloon is rising vertically up with a velocity of 29 m/s. A stone is dropped from it and it reaches the ground in 10 seconds. The height of the balloon when the stone was dropped from it is (g = 9.8 m/s^2)

A stone dropped from top of a building reaches the ground in 7 seconds. The height of tower is ............... m (take g=10m/s^2)

A body dropped from a height H reaches the ground with a speed of 1.2 sqrt(gH) . Calculate the work done by air friction.

A stone drop from height h reaches to earth surface in 1 sec. if the same stone taken to moon and drop freely then it will reaches from the surface of the moon in the time (the 'g' of moon is 1/6 times of earth)-

A stone dropped from a building of height h and it reaches after t second on the earth. From the same building if two stones are thrown (one upwards and other downwards) with the same speed and they reach the earth surface after t_(1) and t_(2) seconds, respectively, then

A body dropped from a height 'H' reaches the ground with a speed of 1.1 sqrt(gH) . Calculate the work done by air friction :
