    Engineering Electrical and Control Engineering: Transfer Function Reduction problem

    Why do i need to refer all signals to the output, if i refer them to the output then i wont have any equasions for the input and i wont be able to calculate Y/V

    Engineering Electrical and Control Engineering: Transfer Function Reduction problem

    But i need to write Y(output)/V(input) function, these equasions are very confusing. Y= fN = (F(p+r))N = F(P(z+m+f)+ROv) p=P(z+m+f) r = Ro=ROv b = Bo=BOv o = Ov f = F(p+r) m = M(b-a) a = A ??? z = Z ??? Can you please show me the solution for a and z, thank you, this methodical way is quite...

    Engineering Electrical and Control Engineering: Transfer Function Reduction problem

    How do i write equasion for output then, even if i wrote for a correctly, i cannot resolve for output signal n = N * y, its only one equasion

    Change of angle if refractive index changes for 10^-6

    Yes, i know how to take the diferentials, but there is no equasion to diferentiate or i dont know it.

    Change of angle if refractive index changes for 10^-6

    Solution: (delta (ϑ)) = -(minus delta n) /(n*sqrt((n^2-1)))

    Average force and angle, collision problem

    Solution is incorrect for angle and force then

    Average force and angle, collision problem

    With what average force and under what angle with respect to the horizontal floor did boy kick the ball if the collision took 0.1 second?

    Average force and angle, collision problem

    I saw some trigonometric identity for this problem but i don't understand it geometrically, any idea?

    Average force and angle, collision problem

    m = 0.1 kg v0 = 10 m/s (x) direction Refractive angle of ball = 30 ° (horizontal) That's the angle of impact. Range of ball = 20 m time of impulse = 0.1 s We are searching for: 1. Angle when the ball was kicked with respect to horizontal. 2. Average force of change in momentum. Solution for...

    Average force and angle, collision problem

    No α ≠ 0, but we are searching for α. α= ?
  22. AncientOne99

    Average force and angle, collision problem

    Probably i need to solve for α first. But because velocity 1 changes both x and y components because of average force i don't find a solution.

    Average force and angle, collision problem

    Homework Statement [/B] Ball with a mass of 0.1 kg travels at a speed of 10 m /s to the boy. Boy kicks the ball with foot so that it bounces back at an angle of 30 degrees with respect to the horizontal floor. The ball falls back to the ground 20 meters from the boy. With what average force...
