Question

Please help me very urgent :((

What is the net force (including direction and magnitude) acting on the object on the above left?

What is the net force (including direction and magnitude) acting on the object on the above right?

Answer 1

-150 N

Step-by-step explanation:

(Newton's second law) F=ma

Sum of forces in Y direction= (+200 N)+(-200 N)= 0...

forces cancel, object does not accelerate up/down

Sum of forces in X direction= (+65 N)+(-65 N)+(-150 N)

= -150 N

notice that the +/- 65 components cancel, leaving a net force of 150 N in the LEFTwards direction (which is typically defined as negative)

Overall, the net force is -150 N
