Question

7. A ball is thrown horizontally from the top of the tower
of height 50 m. If the stone hits the ground at a distance
of 20 m from the foot of the tower, calculate the veloc-
ity with which the ball was thrown.​

Answer 1

Answer:

Horizontal is the opposite of vertical. ... Anything parallel to the horizon is called horizontal. As vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right.
