Two particles start from the same point with different speeds but one moves along `y=a sin omega x` and other moves along curve `y=cos omegax`

Two particles start from the point (2,-1), one moves 2 units along the line x+y = 1 and the other moves 5 units along the line x-2y = 4. If the particles move upward w.r.t coordinates axes, then find their new positions.

Two particles start from the point (2,-1) one moving 2 units along the line x+y=1 and the other 5 units along the line x-2y=4. If the particles move towards increasing y, then their new positions are

Two particles start from point (2, -1), one moving two units along the line x+ y = 1 and the other 5 units along the line x - 2y = 4, If the particle move towards increasing y, then their new positions are:

Three particles start from the origin at the same time, one with velocity u_1 along the x-axis, the second with velocity u_2 along the y-axis . Find the velocity of the third particles, along the x=y line so that the three particles may always lie on the same straight line.

Three particles start from origin at the same time: one with velocity v^(1) along positive x-axis, the second along the positive y-axis with a velocity v^(2) and the third along the line y = x with such a speed that all the three always stay in a straight line, then velocity of the third particles is:

Three particles start from the origin at the same time, one with a velocity v_(1) along the x-axis, second along the y-axis with a velocity v_(2) and third particle moves along the line x = y. The velocity of third particle, so that three may always lie on the same line is:
