A piling for a high-rise building is pushed by two bulldozers at exactly the same time. One bulldozer exerts a force of 1250 pounds in a westerly direction. The other bulldozer pushes the piling with a force of 2650 pounds in a northerly direction. What is the direction of the resulting force upon the piling, to the nearest degree?

a.
65 n of w
b.
25 N of W
c.
45 N of W
d.
35 N of W

Respuesta :

Answer:

Resultant force will act on 65° N of W.

Step-by-step explanation:

As given in the question one bulldozer exerts force of 1250 pounds in western direction and 2650 pounds in northern direction and we have to find angle A which is an angle between 1250 pounds of force and resultant force F.

Therefore tan A= Force on North direction/ Force on west direction = 2650/1250 = 2.12

⇒[tex]A=tan^{-1}(2.12)[/tex]

A = 64.75

A = 65° North of west.
