Three particles start moving from the origin at the same time. Particle 1goes in x-direction with velocity v1 and 2nd in y-direction with v2. Particle 3 goes along line y=x and velocity v3. Show if all three particles remain on same straight line in subsequent motion then v3=√2*v2v1/(v2+v1)

Question

Vikas TU · Answer

Find the distance at any time taken as cinstant suppose take t = 1 s and then we can caluclate velocity later on. . For x – axis, x = V1 For y-axis y = V2 for y=x, x0 = V3cos45 and y0 = V3sin45 Now U have two points. (x,y) and (x0 , y0) Find the eqn. of line using this and find the intersection point with y=x.
