Question

A particle is projected from origin with speed 10m/s at an angle of 37deg with the horizontal. Acceleration of the particle is (-2i-2j) m/s^2. Find-
Time and position of particle when it will cross Y-axis

Answer 1

Explanation:

C

horizontal straight line



Vel of 1st w.r.t. 2nd is horizontal and relative acceleration is zero as both have same acceleration so path is horizontal straight line.
