A particle of mass 2kg moves with an initial velocity of v→=4iˆ+4jˆms^−1. A constant force of F→=20jˆN is applied on the particle. Initially, the particle was at (0,0). The x-coordinates of the particle when its y-coordinates again becomes zero is given by 0). The x-coordinates of the particle when its y-coordinates again becomes zero is [...]
