Ski Jumper's Initial Velocity - Solve the Problem

AI Thread Summary
To determine the ski jumper's initial velocity, the problem requires resolving the final velocity into its horizontal and vertical components. The jumper lands 51.0 m horizontally with a final velocity of 23.0 m/s at an angle of 43.0 degrees below the horizontal. By applying kinematic equations and considering the effects of gravity, the initial velocity can be calculated. The discussion emphasizes the importance of understanding the relationship between the components of velocity and the influence of gravitational acceleration. Ultimately, the solution involves using the given data to backtrack to the initial conditions of the jump.

Homework Statement


After :Leaving the end of a ski ramp, a ski jumper lands downhill at a point that is displaced 51.0 m horixontally from the end of the ramp. His velocity, just before lenading, is 23.0m/s and points in a direction 43.0 degress below the horizontal. Neglecting air resistance and lift he experiences while airborne, find his initial velocity (magnitude and direction) when he left the end of the ramp. Express the direction as an angle relative to the horizontal.



Homework Equations


x = 1/2at(squared) +vot +xo


The Attempt at a Solution


Thinking I should use the final velocity and figure out how much the acceleration of gravity has effected it, just need some guidance there.

Yeap you are correct you just have to resolve the velocity into the x and y component.

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}...

Thread 'Struggle to understand the concept of the 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...
