A stone is thrwon vertically upwards. On its way is passes point A with a speed v and passes point B, 30 m higher than A with speed `(v)/(2)`. Find (i) The speed v (ii) The maximum height reached by the stone above point B.

A stone is thrown vertically upwards with an initial speed u from the top of a tower, reaches the ground with a speed 3 u . The height of the tower is :

A stone is thrown vertically upwards with an initial speed u from the top of a tower, reaches the ground with a speed 3 u . The height of the tower is :

A stone with weight W is thrown vertically upward into air with initial speed u. Due to air friction a constant force R acts on the stone, throughout its flight. Find – (a) the maximum height reached and (b) speed of stone on reaching the ground.

A stone is thrown vertically upward with a speed of 28 m/s. (a) Find the maximum height reached by the stone. (b)Find its velocity one second before it reaches the maximum height. (c)Does the answer of part b change if the initial speed is more than 28 m/s such as 40 m/s or 80 m/s?
