Jordan wants to safely be able to move a cart up a ramp and onto a truck. To see which ramp would be beneficial, he experiments to see how the length of the ramp changes the amount of force needed. Which of the following conclusion can he make from his experiment about how to safely move the cart?

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

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
