Projectile Motion: Finding Initial Velocity

AI Thread Summary
The discussion focuses on using the range formula R = Vo^2 x sin(angle) / gravity to find the initial velocity in projectile motion. It clarifies that Vo represents the resultant velocity, not just the components in the X or Y directions. Additionally, a correction is noted that the formula presented is not entirely accurate. Understanding the correct application of this formula is essential for solving projectile motion problems effectively. Accurate calculations are crucial for determining the trajectory of projectiles.

Hello,

When trying to find initial velocity in Proyectile motion can I use the formula or Range: R=Vo^2 x sin angle / Gravity

The question is if the velocity I get through that equation will be the vector in X, Y or the resultant one?

Thanks

Hello, can you please help me with my question about the range,

thanks
 
Welcome to PF :smile:

Vo refers to the resultant velocity.

By the way, the range formula is not quite correct as written:
R=Vo^2 x sin angle / Gravity
 

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
