Jon and Jim push a dead car forward to the gas station. Jon pushes with 90N while Jim pushes 80 N.
Nina [5.8K]

The resultant of the two forces is about 170 N.

<h3>What is the resultant force?</h3>

The term resultant force has to do with the single force that has the same magnitude and direction as two or more forces acting together.

In this case, the both forces are acting in the forward direction. This implies that the resultant force is 90 N  + 80 N = 170 N.

A certain corner of a room is selected as the origin of a rectangular coordinate system. If a fly is crawling on an adjacent wal
lisov135 [29]

Answer:

S=2.693m

Explanation:

Let point O be the origin of the room and the fly is crawling at point P as shown in the attached photo:

#Distance of the fly from the corner of the room is defined as:

OP=S=\sqrt{{(x_1-x_0)^2+(y_1+y_0)^2}

#Substitute the coordinate values in the above equation:

S=\sqrt{{(2.6m-0m)^2+(0.7m-0m)^2}}\\=\sqrt{7.25}\\=2.693m

Hence, the distance of the fly from the corner of the room is 2.693m
