Part A: Suppose the direction of the force changes from a 48° angle with the
floor to a 70° angle with the floor. Determine the effect on the horizontal and
vertical components of the force. Give forces to the nearest hundredth of a
unit

Horizontal Component of Force decreases and Vertical Component Increases.

Step-by-step explanation:

The rectangular components of a Force are given by:

Horizontal Component:

Vertical Component:

Here, F represents the magnitude of the Force and Θ is the angle between the Force F and the horizontal.

The initial value of Θ is 48 degrees. So under this condition the rectangular components will be:

On increasing the angle to 70 degrees, the new rectangular components will be:

From the above calculations we can see that on increasing the angle made by the Force with floor from 48 degrees to 70 degrees:

If the value of Force F is known, the exact value of rectangular components can be calculated from the previous expressions.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
