Question

A particle is projected from a horizontal plane (x-z plane) such that its velocity vector at time t is given by v = ai + (b-ct)j . its range on the horizontal plane is given by__? a)ba/c b) 2ba/c c) 3ba/c d) none of these

Answer 1

If two vector can be representated boyh in magnitude and direction by the two sides of a triangle taken insame order , then their resultant is representated both in magnitude and direction by the third side of a triangle taken in opposite direction . suppose we have two vectors A and B then their resulant vector is the sum of these two.R=A+B
