Force Problem: Four concurrent forces are applied to a 5 Kg mass: 50 N North, 25 N East, 35 N South, and 35 N West.
Kaylis [27]

A) Net horizontal force:
Fx= -35 + 25 + -10N

Net vertical force
Fy= 50 - 35 = 15N

Net force
F^2 = fX^2 +Fy^2
F= 18N

B.) Acceleration of system
a=18/5=3.6m/s^2

C). Equilibriant force must be equal to the net force above
F1= 18N

D.) Acceleration becomes half
a1= a/2 =1.8m/s^2

E.) Equilibrant force also doubles
F" = 2F' = 36N

You drive in a straight line at 22 m/s for 12 miles, then at 30 m/s for another 12 miles. (a) How does your average speed sav co
Setler [38]

Answer:

Explanation:One method of calculating average speed is to divide the total distance by the total time spent

d1=d2= 12 miles

d1=d2= 19312.1 m

t1=\frac{d1}{u1} \\t1=19312.1/22\\t1=877.8 secs

t2=\frac{d2}{u2} \\t2=19312.1/30\\t2=673.7 secs

u_a=\frac{d1+d2}{t1+t2} \\u_a=25.385 m/s

There is slight difference between the average speeds  due to the reason that average speed is not just the midpoint of the speed but is the total distance traveled by total time.
