AI Thread Summary
An object dropped from a cliff takes 1.80 seconds to reach the water, and the problem can be solved using the principles of free fall. The initial velocity is zero since the object is dropped, and the acceleration due to gravity is known. By applying the kinematic equation for distance traveled under constant acceleration, the height of the cliff can be calculated. The discussion highlights that sufficient information is available to find the solution despite initial doubts. Therefore, the height of the cliff can be determined using the provided time and gravitational acceleration.

An object dropped from the top of a cliff takes 1.80 s to hit the water below. What is the height of the cliff?



I do not know of any equation that would work as only one piece of information has been given



I could not even begin my calculations as I lacked information. Is it possible to solve this question?

You know the time, you know the acceleration (free fall), you know the initial velocity ("dropped" means vo=0). You can find the distance traveled.
 
Thanks!
 

Thread 'Errors and significant figures'

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...
