Josh has a mass of 80 kg. He must apply 800 N of force to climb a rope 5 meters high
How much work did he do?

where are the vectors ?

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

answer is slate

hope this
