Question

A body of mass 5kg moves with an initial velocity of v=4i+4jm/s A constant force F=-50jN is applied on the body is at (0,0) .The X-co-ordinate of the body when it's Y-co-ordinate again become Zero is​

Answer 1

Answer:

Mg+2HCl→MgCl  

2

​  

+H  

2

​  

 

1 mol of Mg is consumed when 1 mol of H  

2

​  

 is produced.

So, 4.2×10  

−3

 mol of Mg is consumed when 4.2×10  

−3

 mol of H  

2

​  

 is produced.

Mass of Mg consumed =n×M=4.2×10  

−3

×24=0.1 g.

Explanation:

Answer 2

Explanation:

See the above solution.

since acceleration along x direction is 0 means velocity along x direction is constant throughout.

Thanks.
