The change in velocity can be calculated using the equation v = gt, where g is the acceleration due to gravity (9.8 m/s^2) and t is the time taken (2 seconds). So, the change in velocity would be 9.8 m/s^2 * 2 s = 19.6 m/s.
The speed of the object after falling for 3 seconds in free fall is 29.4 m/s.
The velocity of a freely falling object 5 seconds after being dropped is approximately 49 meters per second (m/s) downwards. This is the velocity an object reaches due to the acceleration of gravity (9.8 m/s^2) acting on it.
Assuming the object is in free fall, the change in velocity will be approximately 19.6 m/s downward. This is calculated using the formula v = at, where acceleration due to gravity is approximately 9.8 m/s^2 and time is 2 seconds.
The final velocity of a dropped object can be calculated using the equation v = gt, where v is the final velocity, g is the acceleration due to gravity (approximately 9.81 m/s^2), and t is the time the object has fallen. Plugging in the values, the final velocity of a dropped object after falling for 3.0 seconds would be 29.43 m/s.
The speed of an object in free fall after falling for 2 seconds is approximately 19.6 m/s.

Diving is generally taken to mean that you start from rest and jump. If Superboy dives off the building, he would initially have had zero velocity, relative to the building.
Acceleration = (change in velocity) / (time for the change)9.8 = (change in velocity) / (2 seconds)9.8 x 2 = change in velocity = 19.6 meters per second .Hint: The mass of the object and the height of the building are there just tothrow you off balance. You don't need either of them to answer the question.
The speed of the object after falling for 3 seconds in free fall is 29.4 m/s.
In two seconds of fall, the speed increases 19.6 meters (64.4 feet) per second. The magnitude of velocity increases by that amount, while the direction of velocity doesn't change.
KE = 1/2 M V2 = 1/2 (2) (20)2 = 400 kg-m2/sec2 = 400 joules

.. You need the height of the building to figure it out..?
