Projectile Motion Question: Solving for Height of Pier Above Water

AI Thread Summary
A swimmer dives off a pier at a speed of 1.80 m/s and lands 0.80 m from the edge. The time of flight was calculated using the horizontal velocity formula, resulting in 0.44 seconds. This time was then used in the vertical motion equation to determine the height of the pier, which was found to be 0.94 meters. The discussion highlights the importance of using correct units and avoiding premature rounding in calculations. Overall, the approach to solving the projectile motion problem was confirmed to be correct.

[SOLVED] Projectile Motion Question

Homework Statement



a swimmer moving at 1.80m/s dives off a pier and hits the water .80 m from the edge of the pier how high is the pier above the water

Homework Equations


Vx=change X /change Time
change Y = Vyi . change Time +1/2 a . (change time)^2

The Attempt at a Solution



i found time with the Vx formula to be .44m/s
then i punched it into the change Y formula to get the height of the pier as 0.94 m

im just wondering if i approached it right and by change i mean the displacement triangle i just don't know how to make the symbol sorry

thanks ahead of time

Looks good, but don't round any of your answers until you get your final answer and your time is supposed to be in units of s, not m/s.
 
woops a typo there and i didnt round on paper i just wanted to make sure i had it right thanks a lot !
 

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...
