Is it vx= dxf/t?CWatters said:Welcome to the forum. Please don't delete the Homework template as it's there for a good reason.
In what direction is the marble released?
You have an equation for the height/position of the platform. Do you know how to get an equation for the velocity of an object from the equation for it's position?
I am not sure if the platform is at a fixed height. That's the whole the whole problem.FactChecker said:Your question confuses me. Is the platform at a fixed height of 70 meters or is it at a changing height of 2.3[t][/2]+ (-)6.5t+70? Also, why would the platform height matter after the marble is released?

Oh, of course. Thanks.CWatters said:It's not the height that matters it's the velocity. I assume the launch velocity (22.5m/s) is relative to the moving platform.
Correction: The height at launch will matter but it's known to be 70m.
I assume that we are talking about an upward vertical release. So we are talking about vertical position -- aka height. We have the height of the platform as a function of time. We do not have anything that would aptly be called "x" or "f".DThes said:Is it vx= dxf/t?
The formula for calculating the velocity of a marble falling from a platform is v = gt, where v is velocity, g is the acceleration due to gravity (9.8 m/s²), and t is time in seconds.
The formula for calculating the distance traveled by a marble falling from a platform is d = (1/2)gt², where d is distance, g is the acceleration due to gravity (9.8 m/s²), and t is time in seconds.
The acceleration of a marble falling from a platform is 9.8 m/s², which is the acceleration due to gravity on Earth.
The factors that can affect the velocity of a marble falling from a platform include the height of the platform, air resistance, and the mass of the marble.
The velocity of a marble falling from a platform increases as it falls due to the acceleration of gravity. However, as it reaches its terminal velocity, the velocity will remain constant until it reaches the ground.
