A30.0-kg crate is initially moving with a velocity that has magnitude 3.90 m/s in a direction 37.0 degrees west of north. how much work must be done on the crate to change its velocity to 5.62 m/s in a direction 63.0 degrees south of east?

area of focus

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
