A projectile of mass 0.552 kg is shot from a cannon, at height 7 m,?

AI Thread Summary
The discussion focuses on calculating various parameters of a projectile launched from a cannon. Key points include determining the vertical component of the initial velocity, the maximum height reached by the projectile, the magnitude of the velocity vector upon impact, the angle of impact with respect to the horizontal, and the horizontal range of the projectile. The projectile has a mass of 0.552 kg, is launched from a height of 7 m, and has a horizontal velocity component of 5 m/s, with gravity acting at 9.8 m/s². Participants are encouraged to show their work for assistance in solving these physics problems. The thread emphasizes the need for clear problem setup to facilitate help.

A projectile of mass 0.552 kg is shot from a
cannon, at height 7 m,
with an initial velocity vi having a horizontal
component of 5 ms.
The projectile rises to a maximum height of
Y above the end of the cannon's barrel and
strikes the ground a horizontal distance X
past the end of the cannon's barrel.
The acceleration of gravity is 9.8 ms^2 :

Determine the vertical component of the
initial velocity at the end of the cannon's bar-
rel, where the projectile begins its trajectory.
Answer in units of ms.

Determine the maximum height Y the pro-
jectile achieves after leaving the end of the
cannon's barrel. Answer in units of m.

Find the magnitude of the velocity vector
when the projectile hits the ground. Answer
in units of ms.

Find the magnitude of the angle (with repect
to horizontal) the projectile makes when im-
pacting the ground. Answer in units of degree.

Find the range"x" of the projectile. Answer
in units of m.

i need some help setting up the problem.
 
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'
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...
