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)
Find the distance at any time taken as cinstant suppose take t = 1 sand then we can caluclate velocity later on..For x – axis,x = V1For y-axisy = V2for y=x,x0 = V3cos45 and y0 = V3sin45Now U have two points.(x,y) and (x0 , y0)Find the eqn. of line using this and find the intersection point with y=x.
