Question

from the top of a tower of vertical height h a ball A is projected vertically upwards with a speed of vo at an angle of 60° with the horizontal. n seconds later a second ball B is projected horizontally with same speed vo. The two balls collide with kne another. find n​

Answer 1

formula used maximum height = (v sino)2/2g

(vsin60)2/2×9.8

(v3/2)2/19.6

(v route3/2*19.6)

v=29.4
