A stone is thrown upwards and it rises to a height 0f 200m. The relative velocity of the stone with respect to the earth will be maximum at :-

Two stones are thrown from the same point with velocity of 5 ms^(-1) one vertically upwards and the other vertically downwards. When the first stone is at the highest point the relative velocity of the second stone with respect to the first stone is,

A ball thrown vertically upward reached a maximum height of 20m What was the velocity of the stone at the instant of throwing up?

A ball thrown vertically upward reached a maximum height of 20 m . What was the velocity of the stone at the instant of throwing up?

From the top of a tower, a stone A is thrown upwards and a stone B is thrown downwards with the same speed. The velocity of stone A, on colliding with the ground is :

A stone thrown vertically upwards takes 3 s to attain maximum height. Find the (i) initial velocity of the stone (ii) maximum height attained by the stone (g = 9.8 m s^(-2))

A stone thrown upwards with speed u attains maximum height h . Ahother stone thrown upwards from the same point with speed 2u attains maximum height H . What is the relation between h and H ?

A stone thrown upwards with speed u attains maximum height h . Ahother stone thrown upwards from the same point with speed 2u attains maximum height H . What is the relation between h and H ?

A stone is thrown vertically upwards. When stone is at a height half of its maximum height, its speed is 10 ms^-1 , then the maximum height attained by the stone is ( g= 10 ms^(-2) )
