Answer» HIIII dear________❤️❤️

good afternoon___________✌️✌️✌️✌️✌️




Let they MEET after t second

If block travels 's'm distance then in same TIME the bullet travells(100-s)m

For block

s=0×t+12s=0×t+12×10×t2×10×t2

For bullet

100−s=100×t+12100−s=100×t+12(−10)×t2(−10)×t2

Solving this;

we GET t=1second
