1.	Two projectiles are thrown simultaneously in the same plane from the same point. If their velocities are `v_(1)` and `v_(2)` at angles `theta_(1)` and `theta_(2)` respectively from the horizontal, then ansewer the following questions The trajectory of particle `1` with respect to particle `2` wil beA. a parabolaB. a straight lineC. a vertical striaght lineD. a horizontal straight line
Answer» Correct Answer - B `V_(12(x)) = v_(1) cos theta_(1) - v_(2) cos theta_(2)` `a_(12(x) = 0 rArr V_(12(y)) = V_(1) sin_(1)^(theta) - V_(2) sin_(2)^(theta)` `rArr a_(12(y)) = 0` `x = v_(12(x)) t …(1)` `y = v_(12(y)) t ….(2)` From (1)& (2) `Y = (V_(12(y)))/(V_(12(y)))`
