As we know that mass of the box is given as

m = 9.5 kg

acceleration of the box is given as

[tex]a = 1 m/s^2[/tex]

so by Newton's II law we can say

[tex]F = ma[/tex]

now we can substitute all the values in it

[tex]F = 9.5 \times 1[/tex]

[tex]F = 9.5 N[/tex]

So it required 9.5 N force to slide it
