The velocity = (location at 40 seconds - location at 20 seconds)/20 in the direction in which the object is moving.
The speed of the the object is 20/5 = 4 metres per second.In order to answer the question in terms of velocity, it is necessary to know the direction of motion because velocity is a vector.
20 meters per second

This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.
In the case of constant velocity (or speed), velocity = distance / time.
The wave's velocity is 16 ft/s in the path of motion. (20*8)/10 0.333 Hz
No it does not. If the velocity is 10 m/s for 10 secs and 0 for another 10 secs, then the average is 5 m/s which is non-zero over the 20 second period. But the instantaneous velocity is zero for the period from 10 to 20 seconds.
There is no answer to your question without knowing the direction of the velocity and of the force application.
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.
It is 20 seconds.
an object uniformly accerlerates over a distance of 100 m in 20 seconds. calculate the acceleration.
