I assume the object starts from rest. The speed will be 16*3 which is 48m/s
Change of speed divided by time gives you average acceleration. For example, a change of 30 m/s during 5 seconds gives you 6 meters per second square - this is the average acceleration during those 5 seconds. If acceleration is constant, then this is also the acceleration at any moment during those 5 seconds. For more complicated functions (non-constant acceleration), derivates (a topic in calculus) has to be used. Specifically, the acceleration is the derivative of the velocity.

Zero, by definition.
The velocity of an object in free fall after 10 seconds is approximately 98 m/s. This value is the acceleration due to gravity (9.8 m/s^2) multiplied by the time in seconds.
an object uniformly accerlerates over a distance of 100 m in 20 seconds. calculate the acceleration.
The speed of a freely falling object 10 seconds after starting from rest is approximately 98 m/s. This is because in free fall, the acceleration due to gravity is approximately 9.8 m/s^2, so after 10 seconds, the object would have reached a speed of 98 m/s.
object to fall with an approximate acceleration of 9.8 seconds.
The speed of the object after falling for 3 seconds in free fall is 29.4 m/s. This is because the acceleration due to gravity is about 9.8 m/s^2, so after 3 seconds the object would have reached a speed of 29.4 m/s.
The acceleration of a freely falling object is approximately 9.81 m/s^2, directed downwards towards the center of the Earth. Therefore, the acceleration of the object 2 seconds after being released will still be 9.81 m/s^2, assuming no other forces are acting on it.
To answer this question we would need to know the acceleration, which is not provided.
60 m/s
After 10 seconds of free fall from rest, an object's speed will be approximately 100 m/s. This is because the acceleration due to gravity is approximately 10 m/s^2, so after 10 seconds, the object will have reached a speed of 100 m/s.
