At the maximum height of its parabolic trajectory, it explodes into two fragments F1 and F2. Fragment F1, with mass M/4, immediately after the explosion, acquires a vertical velocity oriented downwards along the negative direction of the Y-axis. The time interval between the instant immediately after the grenade explosion and the instant when fragment F2 touches the ground is: Data: Neglect air resistance, consider the magnitude of the acceleration due to gravity to be equal to g, and assume that the trajectories of the grenade and the fragments are only on the XY axis. #espcex #efomm #eear #afa #escolanaval
