Question
The velocity $v$ of a falling object is directly proportional to the time $t$ of the fall. If, after 2 seconds, the velocity of the object is 64 feet per second, what will its velocity be after 3 seconds?
Step 1
This can be written as: \[v = kt\] where $k$ is the constant of proportionality. Show more…
