Projectile Motion - Finding theta

AI Thread Summary
The discussion focuses on solving a projectile motion problem using a graphed parabola with time intervals of 0.1000 seconds. Key values identified include total time (Tt) of 2.000 seconds, range (R) of 14.50 cm, and maximum height (H) of 10.00 cm. The main challenge is determining the initial velocity (V0) and launch angle (θ) from these values. It is suggested to analyze the x and y components separately to derive V0 in both directions. The conversation emphasizes the importance of understanding the relationships between the variables to solve for the unknowns effectively.

Homework Statement


Iv'e been given a graphed parabola with each x interval at 0.1000s. From this I need to find R, Tt, H, V0, a and θ.

Homework Equations


Tt= 2 (Vsinθ/g)
R= (V2sin2θ)/g
H=(Vsinθ)2)/2g

The Attempt at a Solution


From observing the graph I know:
dx and dy at every 1/10 of a second.
Tt= 2.000s
R= 14.50cm
H= 10.00cm

From here I have no idea how to find V0 or θ. I'm not sure what one I have to find first in order to get the other. Any help is appreciated.

it sounds like you were given the distance that the object traveled and its max height through this graph

by looking at the x-direction and y-direction separately, you should be able to determine the initial velocity in both the x and y directions
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
