Explanation:
W.D. = F * s = 50N * 2m = 100J.

Terminal velocity is the maximum velocity attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object.(Wikipedia)
The answer is 111.
Using Newton's Second Law, F=ma, plugging known values in we get:
F = (79kg)(1.4m/s^2) = 110.6N ≈ 111N
To see which way atmospheric conditions and meteorological phenomena are moving, and how fast.
Also to see whether they were correct yesterday.
