Barnaby · Answer 1

The formular for solving this equation is

mgh = mv^2/2

The M on both sides of the equation stand for mass and the two of them cancel each other out and the equation becomes:

gh = V^2 / 2

g = 9.8 m/s

h = 1.23 m

V?

V is the velocity that we need to find, so we are going to make V the subject of the formular:

V = Square root of 2gh = square root of [2 * 9.8 * 1.23] = square root of [24.108] = 4.9

Thus, the velocity = 4.90 m/s
