Question

Two forces with magnitudes of 150 and 75 pounds act on an object at angles of 30° and 150°, respectively. Find the direction and magnitude of the resultant force. Round to two decimal places in all intermediate steps and in your final answer. (2 points)

Answer 1

Answer:

The resultant force magnitude is  129.90 pounds at angle of 60°

Step-by-step explanation:

Two given forces and resultant force form right triangle. The first force (150 pounds) is hypotenuse, the second force ( 75 pounds) and resultant force are right sides of the right triangle.

Then we can write pythagorin theorem

R= √150∧2 - 75∧2 = √ 22500-5625 = √16875 = 129.90

Good luck!!!
