Answer 2

Calculation of the Velocity of a Falling Object

To find the velocity of an object that freely falls for 5 seconds without an initial velocity, we can use the equation of motion for free fall:

v = gt

where: - v is the final velocity of the object - g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth) - t is the time of fall

In this case, the time of fall is 5 seconds. Substituting these values into the equation, we get:

v = (9.8 m/s^2) * (5 s) = 49 m/s

Therefore, the velocity of the object at the moment it hits the ground is 49 m/s.
