Which is the best example of force acting in the same direction

B. Two football players pushing a tackling sled.

Explanation: Because it asks what is the best example of forces acting in the SAME direction, it will be two football players pushing a tackling sled. This means, since the two football players are both pushing the sled, they will also be pushing it at the same time in the same direction.

Hope this helped. :)

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
