Aplane flies along a straight line path after taking off, and it ends up 210 km farther east and 90.0 km farther north, relative to where it started. what is the plane's displacement?

The plane's displacement is 228.47 km.

Explanation:

It is given that,

Distance covered in east direction is 210 km and distance covered in north direction is 90 km. Let d is the plane's displacement. It is equal to the shortest path covered by the particle.

d = 228.47 km

So, the plane's displacement is 228.47 km. Hence, this is the required solution.

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
