Answer 2

Calculation of Initial Velocity

To find the initial velocity of an object, we can use the equation of motion:

v^2 = u^2 + 2as

Where: - v is the final velocity (12 m/s in this case) - u is the initial velocity (what we want to find) - a is the acceleration (which we assume to be zero since no acceleration is mentioned) - s is the displacement (2.4 m in this case)

Rearranging the equation, we get:

u^2 = v^2 - 2as

Substituting the given values:

u^2 = (12 m/s)^2 - 2 * 0 * 2.4 m

Since the acceleration is zero, the equation simplifies to:

u^2 = (12 m/s)^2

Taking the square root of both sides, we find:

u = 12 m/s

Therefore, the initial velocity of the object is 12 m/s.
