5.2. Do I just sub it into the second equation with t-2 and solve for initial velocity?gneill said:Your Relevant equation should suffice.
What value did you get for the time of fall for the first stone? So what must be the time (numeric value) that the second stone has to make the complete journey?

So the speed of sound is irrelevant?haruspex said:Sure.

Initial velocity is the velocity of an object at the beginning of its motion.
To calculate initial velocity for a falling object, you can use the formula v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration due to gravity (usually -9.8 m/s²), and t is the time the object has been falling.
The acceleration due to gravity is a constant value of -9.8 m/s² on Earth. However, if you are on a different planet or in a different environment, you can look up the specific acceleration due to gravity for that location and use it in the formula to calculate initial velocity.
Yes, initial velocity can be negative. A negative initial velocity indicates that the object is moving downwards at the beginning of its motion.
Air resistance can decrease the initial velocity of a falling object. This is because air resistance acts in the opposite direction of the object's motion, causing it to slow down. However, for most practical purposes, the effects of air resistance can be ignored when calculating initial velocity.
