Solving Gravity: Initial Velocity & Time

AI Thread Summary
It is possible to determine the acceleration due to gravity using initial velocity and the time taken for an object launched vertically to return to the ground. The relevant equation relates these variables, typically expressed in kinematic equations. The discussion emphasizes a desire to solve the problem independently, despite seeking guidance on the formula. Participants are encouraged to explore the physics behind the motion rather than simply relying on provided formulas. Understanding these concepts is crucial for accurately calculating gravitational acceleration.

I guess this isn't the proper format, but I would rather try and work out the complete problem on my own :\ If this is a huge faux pas then someone can go ahead and delete this post i suppose.

Now that that's out of the way, could someone tell me if it is possible to determine acceleration due to gravity knowing only the variables for initial velocity and time taken to once again reach to ground of an object launched from the ground vertically? And what would this equation be?

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'
Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
