A shell is projected by a cannon at an angle `30^(@)` with the vertical for a horizontal range `R`. It explodes at the highest point of its trajectory. Now match the column `I` and `II`.

A stone is projected with speed of 50 ms^(-1) at an angle of 60^(@) with the horizontal. The speed of the stone at highest point of trajectory is

Match the column I w.r.t column II

A shell is fired from a cannon with a speed of 100 m//s at an angle 30^(@) with the vertical ( y -direction). At the highest point of its trajectory, the shell explodes into two fragments of masses in the ratio 1:2 . The lighter fragment moves vertically upwards with an initial speed of 200 m//s . What is the speed of the heavier fragment at the time of explosion?

Select correct match w.r.t. column I & II
