Choose the situation below in which the force applied is the greatest.
A) Steve put in 50 J of work moving a box 50 meters.
B) Doing 400 J of work, Penny pushed her cat 80 meters.
C) Samantha did 365 J of work dragging a wagon across 73 meters of lawn.
Eliminate
D) Clark pushed a crate from the chair, 16 meters across the room, doing 144 J of work.

D

Explanation:

We know the formula for Work to be:

W = f * d

Where W is work done

f is force

d is the distance

A)

Work = 50

Distance = 50

So, Force is:

Force = 50/50 = 1

B)

Work = 400

Distance = 80

Force = 400/80 = 5

C)

Work = 365

Distance = 73

Force = 365/73 = 5

D)

Work = 144

Distance = 16

Force = 144/16 = 9

Hence, D is the situation in which the force applied is the greatest.

mass and volume are the answers you are looking for

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
