A parachutist jumps from a plane and free falls. Sometime after falling, his velocity is 25m/s. How Far has the parachutist fallen?

i think its

the plateau is likely to turn into a desert do to corrosion.

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
