Two forces of 50 N and 30N respectively, are acting on an object. Find the net force (in N) on the object if

A) the forces are acting in the same direction.. B) Together, forces are acting in opposite directions

A) 80 N

B) 20 N

Explanation:

A) If the forces acting are in the same direction, then the net force will be a sum of both so many faces..

Thus;

ΣF = 50 + 30

ΣF = 80 N

B) If the forces are acting in the in opposite directions with the larger force pointing in the positive y-axis then, the net force is;

ΣF = 50 - 30

ΣF = 20 N

this means that the temperature of both substances will be equal
