Motion in A Str...

A balloon starts rising from the ground with an acceleration of $$1.25 \;ms^{-2}$$, After $$8$$ seconds, a stone is released from the balloon, The stone will 
$$(g=10\;ms^{-2})$$

A ball is dropped from the top of a building. The ball takes $$0.5$$ s to fall past the $$3$$ m length of a window at certain distance from the top of the building. 
($$g=10\;m/s^{2}$$)
How far is the top of the window from the point at which the ball was dropped ?

A stone is dropped from the $$16^{th}$$ storey of a multistoried building reaches the ground in $$4$$ seconds. The no. of storeys travelled by the stone in $$2^{nd}$$ second is

A ball is dropped from the top of a building. The ball takes $$0.5s$$ to fall past the window of $$3m$$ in length at certain distance from the top of the building. ($$g=10m/s^{2}$$) How fast was the ball going as it passed the bottom of the window?

A body falls from a height of $$200$$ m. If gravitational attraction ceases after $$2$$ s, further time taken by it to reach the ground is ($$g=10 \;ms^{-2}$$)

A ball is dropped from the top of a building. The ball takes $$0.5$$ s to fall past the $$3$$ m length of a window at certain distance from the top of the building.  Time of travel above the window is (Take $$g=10\;m/s^{2}$$)

A body thrown vertically up with a velocity $$u$$ reaches the maximum height $$h$$ after $$T$$ seconds.Which of the following statements is correct?

A juggler throws up balls at regular intervals of time. Each ball takes $$ 2\ s$$ to reach the highest position. If the first ball is in the highest position by the time the fifth one starts, then the separation between the first and the second balls is

A bag is dropped from a helicopter rising vertically at a constant speed of $$2$$ $$m/s$$. The distance between the two after $$2$$ s is (Given $$g=9.8m/s^2$$)

A body throws balls vertically upwards. He throws one, while the previous one is at its highest point. Maximum height reached by a ball if he throws one ball each per second at uniform speed is
