A paratrooper id dropped from an airplane. After some time his parachute opens and he reaches the ground with almost zero speed. This speed of fall (v) versus time (t) grapg will look like :

A boy is cycling at a constant speed. His distance versus time graph will look like

A parachutist drops freely from an aeroplane for 10 seconds before the parachute opens out.Then he descends with a net retardation of 2m//sec^(2) . His velocity whe he reaches the ground is 8m/sec.Find the height at which he get out of the aeroplane?

A parachutist after bailing out falls freely for 50 metres. Then his parachute opens and he falls with deceleration of 2ms^-2 When he reaches the ground his speed is reduced to only 3 metres per seconds. at what height did he bail out ? For how long was he in air ?

A parrachutist bails out from an aeropane and after dropping through a distance of 40 m opens the parachute and decelerates at 2 ms^(-2) . If he reaches the ground with a speed of 2 ms^(-1) , how lowg he in the air ? At what height did he bail out from the plane ?

A stone is thrown upwards from the top of a tower with some initial speed and it reaches the ground in second. Now it is allowed to fall with the same initial speed downward and it reaches the ground in 1 second In how much time will it reach the ground if the stone is allowed to fall freely under gravity from the same place:
