Forces in direction x:
fx1 = 100 * cos (50) = 64.28
fx2 = 50 * cos (160) = - 46.99
The resultant is:
fx = fx1 + fx2 = 17.29
Forces in direction y:
fy1 = 100 * sine (50) = 76.60
fy2 = 50 * sine (160) = 17.10
The resultant is:
fy = fy1 + fy2 = 93.70
The magnitude of the resulting force is:
f = root (fx ^ 2 + fy ^ 2)
f = root ((17.29) ^ 2 + (93.70) ^ 2)
f = 95.28
The angle is:
theta = atan (fy / fx)
theta = atan (93.70 / 17.29)
theta = 79.55 degrees
Answer:
The direction and magnitude of the resultant force are:
f = 95.28 pounds at theta = 79.55 degrees
Answer:
y=7
Step-by-step explanation:
It has to be go in the opposite direction and x=4 so the answer will have to be y=something and if the line has the point (5,7) then the line must be y=7
Answer:
Step-by-step explanation:
64x³-64x²-9x+14
Answer:
13 - 17
Step-by-step explanation:
Using the rule
× = a
Each term in the second factor is multiplied by each term in the first factor, that is
2 ( - 9 ) + 1 ( - 9 )
Distribute both parenthesis
= (2 × 11) - 18 + - 9
= 22 - 17 - 9
= 13 - 17
