a stone thrown horizontally from the top of a vertical wall with a velocity of 15m/s, hits the horizontal ground at a point 45m from the base of the wall. calculate the height of the wall. g =10m/s

The height of the wall is 45 m

Explanation:

Horizontal Motion

When an object is thrown horizontally with an initial speed v from a height h, the maximum horizontal distance traveled by the object, also called the range can be calculated as follows:

If we know the range and want to calculate the height it was thrown from, we solve the equation for h:

We'll use the approximate value of g=10\ m/s^2.

The stone was thrown from the top of a wall with a speed of v=15 m/s and it hits the ground d=45 m away from the base of the wall. Calculating:

h = 45 m

The height of the wall is 45 m
