The discussion revolves around a problem involving acceleration as a function of velocity, specifically examining the relationship between velocity and acceleration over a defined time interval. The original poster presents a scenario where velocity is expressed as a function of acceleration, leading to confusion regarding the units and the formulation of the equations.
The discussion is ongoing, with participants raising questions about the units of the constant in the equation and the validity of the expressions used. Some guidance has been offered regarding the relationship between acceleration and velocity, but no consensus has been reached on the correct interpretation of the problem.
Participants note potential confusion stemming from the original problem statement and the definitions of the variables involved. There is an acknowledgment of the need for clarity regarding the units of measurement and the implications of the equations presented.

When 2<=t<=6
v= 4/a in ft/sec2
v= 6 ft/sec @ t=2s
Find a at t=3s

a=dv/dt.
The Attempt at a Solution
My integration is horribly wrong and honestly not worth typing. LOL
Spinnor said:You write,
v= 4/a in ft/sec^2
something is goofy here, something is not right?
Spinnor said:Now you have acceleration = 4/velocity what are the units of the 4
acceleration * time has units of velocity. Your expression a=4v^-1 still confuses me. Does the number 4 have units? I'm missing something that others might be missing as well.
