A string is now attached to the block and it is pulled up the incline $($ the string is parallel to the

incline surface$)$ with a tension force of $40$ N$.$ The block slides up at a constant speed of $1\mathrm{.}5$ m$/$s$.$ The

coefficient of kinetic friction between the incline and block is:

a$)0\mathrm{.}53$

b$)0\mathrm{.}58$

c$)0\mathrm{.}63$

d$)0\mathrm{.}68$

e$)$ more information is needed to determine
