Physics 10: Calculating Velocity of a Ball Launched from a Slingshot

AI Thread Summary
To calculate the velocity of a ball launched from a slingshot, the relevant parameters include the mass of the ball (0.675 kg), the force applied (3.50x10^2 N), and the distance pulled back (1.75 m). The potential energy stored in the slingshot can be calculated using the formula Ep(elas) = force x distance. This energy can then be converted into kinetic energy to find the velocity of the ball at release. The discussion emphasizes the need to determine which values—force or energy—are most useful for the calculation. Understanding these concepts is crucial for solving the problem effectively.

Here's the question:
1. A ball with a mass of 0.675 kg was launched towards a wall. If it was pulled back a distance of 1.75 m in the slingshot using 3.50x10^2 N of force, what is the speed of the ball as it is released from the slingshot?
2. Ep(elas)=fxd?? that could possibly be divided by the mass to give you velocity
3...
I really have no idea and I really need help.

They gave a spring constant and a distance. You can get both force and energy values from those given quantities. Which one do you want? In other words, what do you want, and which value will be more useful in obtaining what you want?
 

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...
