Solving for the Angle of a Baseball's Velocity in Projectile Motion

AI Thread Summary
The problem involves a baseball sliding off a 1.3 m high table and landing 0.7 m away, with gravity at 9.81 m/s². The initial velocity is horizontal as the ball leaves the table. To find the angle of the ball's velocity just before impact, the x and y movements must be analyzed separately. The vertical motion can be calculated using the time it takes to fall, while the horizontal distance helps determine the final velocity components. The resulting angle can then be calculated using trigonometric functions.

Homework Statement



A 72 g autographed baseball slides off of a
1.3 m high table and strikes the floor a hori-
zontal distance of 0.7 m away from the table.
The acceleration of gravity is 9.81 m/s2 .

What was the direction of the ball’s velocity
just before it hit the floor?
That is, at what angle (in the range −90◦ to
+90◦ relative to the horizontal directed away
from the table) did the ball hit the floor?
Answer in units of degrees

Hi lev1234! Welcome to PF! :smile:

The ball slides off the table, so its initial velocity is horizontal.

Treat movement in the x and y directions separately.
 

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'

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...
