Initial Velocity Given Distance, Angle, and Initial Height

AI Thread Summary
To determine the muzzle velocity of a projectile launched at a 45-degree angle from a height of 25.6 cm and traveling a distance of 119.2 cm, kinematic equations of motion should be utilized. The projectile's motion can be analyzed using separate equations for vertical and horizontal components due to the angle of launch. The absence of air resistance simplifies the calculations, allowing for a focus on gravitational effects. Further assistance can be provided with specific equations and explanations if needed. Understanding these principles is crucial for solving the problem effectively.

Homework Statement


Given your assigned projectile launcher determine the muzzle velocity.

angle of launcher = 45degrees
distance to bottom of barrel = 25.6 cm
distance traveled when fired = 119.2cm

Ignore Air resistance

Homework Equations



I don't know where to start since I have an angle.



The Attempt at a Solution



I don't know where to begin since the projectile is basically starting from a platform at an angle.

Start with the Kinematic equations of motion.

Since the cannon ball is fired at an angle, it should have 2 sets of equation (vertical and horizontal).

That should set you off. If you need help, reply back here and I will give you the equations with an explanation.
 

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...
