Answer 1

Answer:

Two identical balls X and Y are projected horizontally from the edge of a cliff. ... The horizontal speed of the ball at R is 1∙2 ms-1. ... The ball hits the ground 1·22 s after it leaves the cliff.

Explanation:

From a cliff of height 28.8 m above the ground, a ball is thrown horizontally with an initial velocity of. 7 m/s. A) 4.2 m. B) 8.4 m.
