AI Thread Summary
To solve the problem of a football punted from an initial height of 0.75 m at a 41° angle, the key equations involve projectile motion, particularly those accounting for vertical displacement. The equation y = y0 + v0t - 1/2 gt² can be used, where y0 is the initial height. Additionally, the equation v² = u² - 2g(y - y0) is relevant for determining the initial speed. The discussion highlights the need for formulas that accommodate non-zero starting heights in projectile motion problems. Understanding these equations is essential for accurately calculating the initial speed of the ball.

Homework Statement



In a football game a ball is punted from an initial height of 0.75 m and at an angle of 41° above the horizontal. If the ball travels a horizontal distance of 38 yd before hitting the ground, what was its initial speed? (Neglect air resistance.)


Homework Equations



I cannot find any information in my textbook relating to problems that have and starting point (y) that is not 0. What formula do I use on these problems? Thanks

The Attempt at a Solution

 
Physics news on Phys.org
y=y0+v0t -1/2 gt2use this where y0 is the initial height.

EDIT: this may help as well

v2=u2-2g(y-y0)
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
