Asled is being pulled across a floor by two ropes such that the angle between them is 60 degrees. if the forces on the ropes are 100 pounds and 80 pounds. what is the resultant of the forces.

58 lb

Step-by-step explanation:

We can draw a vector triangle with the 100 lb force vector starting at the tip of the 80 lb vector. Then the resultant force vector C will be the third side of the  

triangle, and the angle opposite this third side will be 180 - 60 = 120 degrees.

Then using the Cosine rule  

C^2 = 80^2 + 100^2 - 2*80*100*cos(120)

       = 3373. 1045

C^2 = 3373.1045

C =  58 lb

The resultant force = 58 lb  

146%

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
