Vanessa runs on the soccer field 20 meters North, then makes a cut to the right going East for 3 meters. What is Vanessa’s displacement from her original spot?

20.2 m

Explanation:

Given that Vanessa runs on the soccer field 20 meters North, then makes a cut to the right going East for 3 meters. What is Vanessa’s displacement from her original spot?

The Vanessa displacement can be calculated by using pythagorean theorem.

Displacement = sqrt( 20^2 + 3^2 )

Displacement = sqrt( 400 + 9 )

Displacement = sqrt( 409)

Displacement = 20.2 m

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
