How to calculate Terminal Velocity from Displacement-Time graph?

Question

I have a displacement-time graph here, and I'm told to calculate the terminal velocity from it. I know that the gradient of the graph would give me the velocity, but would this be the terminal velocity requested? Kinda puzzled. Thanks in advance.

Answer 1

Once an object reaches terminal velocity, acceleration = 0. Thus, you'll be able to determine the terminal velocity by finding an area of the graph where it's a straight line, then taking the slope.
