Homework Statement I know that k*u^3=F And I have data of when you change Z , so for example if Z is 3, then u is 5 and F is 3. And i need to get the function with only Z and F without u, how do I do it?The Attempt at a Solution I made a function through excel with Z and F but because U also...

Omg, idk where i got the 10meters. I mean the 1 meters because it's 1 meter above the floor. So the combined movement of the elevator and the bag dropping should be 1 meter?

Okay, thanks! But why can't I think like this. I have 10t=y and (9.82t^2)/2=y Then I put some diffrent times for example 0.3 in both and I get that the elevator moved 3m up, and the elevator 0.4419m down. And then I try until the sum of the both is 10? And how do I solve your equation?

You're right I don't really understand it and I'm totally new to this. I'm doing this on my free time, and just thought about this question :p But could you explain y=y0+vt−0.5gt^2 ? What does y stand for? And could you please put the solve the equation?

is it correct to solve this equation to get the time it takes for it to fall down, because the total distance the elevator and the bag travels is 10? (9.82x^2)/2+10x=10 x=0.73 Is this the correct time the bag travels? Or since do i need to have one negative and get (9.82x^2)/2-10x=10 x=2.77...

It just falls? Can anyone show me the solution, or atleast explain it please?

Homework Statement 1. John is traveling with an elevator upwards with the speed of 3.0m/s. She drops her bag. How big will the acceleration be right before it hits the elevator floor? My answer is 9.82m/s^2 is that correct? 2. Assuming the bag is 1 meter above the floor with an weight of 1 kg...
