2006年7月31日 · can anyone explain 1)first angle projection 2)third angle projection what are the advantages & disadvantages of the above why not use second and fourth angle.

2020年12月8日 · Homework Statement Three particles are projected in the air with the minimum possible speeds (particle at point A with u1,at B with u2 and at point C with u3), such that the first goes from A to B, the second goes from B to C and the third goes from C to A. Points A and C are at the same horizontal level. The two inclines make the same angle α with the horizontal, as …

2021年3月29日 · The diagram represents the vector relationship Angle is the angle of projection and angle is complementary to since triangle ADB is a right triangle. At point D the projectile has zero vertical velocity meaning it has reached its highest point. The significance of the right angle marked at vertex A will be explained a little later. Horizontal projectile range R is related to the …

2021年6月8日 · These would be relations between the five basic parameters and physical quantities provided in the statement of the problem. Projection angle optimization Projectile motion problems sometimes require finding the optimum projection angle at which the horizontal range or the vertical distance or the initial speed are at an extremum.

2012年5月8日 · I have 2 vectors in 3d space, v1 and v2. I also have a vector representing as it happens the direction of the Earth's magnetic field, called h. i believe that v1 and v2 are related in that v2 is some rotation around h of v1. i would like to find that angle of rotation. i can't just find...

2007年12月22日 · [SOLVED] simple projectile motion.. Homework Statement A projectile is fired in such a way that its horizontal range is equal to 3 times its maximum height. What is the angle of projection? Homework Equations whole bunch for proj motion. The Attempt at a Solution I …

2015年7月28日 · Homework Statement : The trajectory of a projectile in a vertical plane is y = √3 x - (1/5)x2, where x and y are respectively horizontal and vertical distances of the projectile from the point of projection. Find the angle of projection and speed of projection. [/B] Homework Equations : 2-Dimensional Equations and maybe calculus. [/B]

2007年8月20日 · A projectile is fired in such a way that its horizontal range is equal to three times its maximum height. What is the angle of projection? If I let A = maximum height (or h), than horizontal range (or R) = 3A. I suppose I can also substitute 1 for h and 3 for R.

2009年12月31日 · How would I calculate the angle of projection to launch a shell R distance with air resistance? Also, I doubt the game calculates air resistance extremely realistically.

2017年10月6日 · When the projectile is shot onto a flat ground, do you know how to find the angle for maximum range? The method is identical here. You are given "R", the range of the projectile. Only this time, you are dealing with two angles, the angle for the initial velocity, and the angle of the inclined plane. For a fix angle of the inclined plane, how would you use "R" to find …
