The wing of an airplane experiences the forces as depicted in the vector diagram to the right. Using both one and two dimensiona
Vedmedyk [2.9K]

Answer:

A.) 3605.6 N

B.) 33.7 degree

Explanation:

To find the result force acting on the wing of the airplane, we need to resolve the forces into x and y components

Resolving into x component :

Sum of forces = 3500 - 500 = 3000N

Resolving into y component:

Sum of forces = 2000N

Resultant force Fr = sqrt ( Fx^2 + Fy^2)

Fr = sqrt ( 3000^2 + 2000^2 )

Fr = sqrt ( 9000000 + 4000000 )

Fr = sqrt ( 13000000)

Fr = 3605.6 N

Therefore, resultant force acting on the wing is 3605.6 N

The direction of the vector will be:

Tan Ø = Fy / Fx

Substitute Fx and Fy into the formula

Tan Ø = 2000 / 3000

Tan Ø = 0.66666

Ø = tan^-1(0. 66666)

Ø = 33.7 degree.

WILL GIVE BRAINLIEST!
Ulleksa [173]

Answer:0kgm/s

Explanation:

Momentum before collision=momentum after collision

Since the momentum of the two blocks have positive sign, it means they are moving in thesame direction

Therefore we use the formula

Momentum (A)+momentum (B)=Momentum (A)+momentum (B)

25+35=60+momentum (B)

60=60+momentum (B)

Momentum (B)=60-60

Momentum (B)=0kgm/s
