How to Solve Horizontal Projectile Questions?

AI Thread Summary
To solve horizontal projectile questions, first determine the time it takes for the stone to hit the ground using the horizontal distance and initial velocity. The vertical motion can be analyzed separately to find the height of the cliff using the time calculated. The impact velocity can be found by combining both horizontal and vertical components, taking into account the gravitational acceleration. Key equations include V = Vo + at, X = Xo + Vot + 1/2at^2, and v^2 = Vo^2 + 2a(change in)X. Understanding these principles is essential for accurately solving projectile motion problems.

Homework Statement



a person sstanding on a cliff throws a stone with a stone horizontal velocoty of 15.0m/s
and the stone lands on the ground 47.0m from the base of the cliff.

a. how much time does it take for the stone to hit the ground?
b. how high was the cliff?
c.what is the impact velocite of the stone(magnitude and derection)

Homework Equations


V = Vo + at
X = Xo + Vot + 1/2at^2
v^2= Vo^2 + 2a(change in)X

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 'A cylinder connected to a hanging mass'

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...
