Formula for vertical throw?
v2=sqrt(2*g*h) v...starting velocity g...gravity h...height achieved
At what projection angle will the range of a projectile equal to its maximum height?
Interesting question! Answer: 75.96... degrees from the horizontal. Let the projectile be launched with speed v at an angle θ degrees above the horizontal. Then its vertical speed component is v sin θ, and its horizontal component is v cos θ. The time of flight is t = 2 v sin θ / g, so that the range R is given by R = v t cos θ = 2 v^2 sin θ cos θ / g. The maximum height is given by H = (v sin θ)^2 / (2 g). (You may think of this is as merely an application of the standard result that, dropping from rest in the second half of the flight, the downward speed u = v sin θ must be related to the downward acceleration a and distance d travelled by u^2 = 2ad. In this context, where a = g and d = H, that is equivalent to the conservation of kinetic plus potential energy, of course.) If R = H, then v^2 sin^2 θ / (2 g) = 2 v^2 sin θ cos θ / g. Therefore sin θ / cos θ = tan θ = 4. Thus θ = arctan (4) = 75.96... degrees.
Prove that the two dimensional motion of a particle in the xy-plane having initial angle θ with the x-axis will be parabolic?
The browser used by this site does not consistently support Greek characters so I will change the angle to w degrees. The direction of the y-axis is taken to be the positive direction so that the upward acceleration due to gravity is -g m/s^2.Suppose the particle is projected with an initial velocity of u m/s at an angle of t degrees.Then the vertical component of v is v(y) = v*sin(w) and the horizontal component is v*cos(w).Suppose the position of the particle after t seconds is [x(t), y(t)].Then, since there is no force acting in the horizontal direction, x(t) = v*cos(w)*tor, more simply, x = v*t*cos(w)this gives t = x/(v*cos(w)In the vertical direction the only force is gravity so y(t) = v*sin(t) - 1/2*g*t^2or, more simply, y = v*t*sin(w) - 1/2*g*t^2substituting for t,y = v*[x/(v*cos(w)]*sin(w) - 1/2*g*(x/(v*cos(w))^2or y = x*tan(w) - 1*g/[(2*v^2*cos(w)^2]*x^2the above equation would look much tidier if only we could write powers as superscript but this crap browser will not allow that.The equation is, therefore, of the form y = ax^2 + bx for some constants a and b. That is, it is a parabola.
Definition of light edge in graph?
"An edge is light edge crossing the cut if its weight is minimum of any edge crossing the cut"So lets say you have a graph G = (V, E), and you partition the vertices in V into to sets A and B= V-A (neither A or B are empty sets). Then the light edges (u, v) in E where either u or v is in A and the other is in B, and where none of the other edges in E that fill this criteria have a shorter weight.
What is the maximum number of edges in an undirected graph with V vertices?
V*(V-1)/2
