Finding Projectile Velocity with a Spring Launcher - Kinematics Equations

AI Thread Summary
To find the projectile velocity of a spring launcher, one can use kinematics equations, focusing on the time of flight until the projectile lands. By measuring the time it takes for the spring to reach the ground after being launched vertically, the initial velocity can be calculated. The launch height may differ from the landing height, which should be accounted for in calculations. Experimentation involves adjusting the spring stretch and measuring the corresponding launch time. This method effectively determines the muzzle velocity of the projectile.

projectile motion --please help :(

Homework Statement



you have a spring launcher and it can shoot springs at angles that you can alter, but you need to find the velocity at the given angle. the velocity you need to find is like muzzle velocity. you're supposed to stretch the spring and it needs to be shot vertically into the air.
also the launch height isn't necessarily the same as when it lands. how would u find this velocity thru experimentation?!

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...
