A particle is initially at the point (0,100 )m. its start moving with constant speed of 1 m/s. The particle moves 1 m in the +x direction and then i m in the – y direction. like this the particle keep on moving till it reaches the x axis . what is the time after which the particle reaches the x axis ?
