A constant force of 10 N act on a block ...

A constant force of 10 N act on a block as shown in figure initial velocity of the block is zero. It is observed from three frames of reference `S_(1),S_(2)` and ground. The frame `S_(1)` start from rest and move with constnat acceleration `10m//s2.` The frames `S_(1)and S_(2)` and block start moving simultaneously at `t=0.`
