What does aerospace engineering have to do with physics

1 answer:

Vilka [71]3 years ago

7 0

Aerospace engineering is related to physics because the career consists of almost all physics. Aerospace engineers work to understand aerodynamics (the motion of air and how it interacts with objects, particularly in the sky). Aerodynamics is a concept in physics, thus aerospace engineers work with physics.

Three people pull simultaneously on a stubborn donkey. Jack pulls eastward with a force of 83.5 N, Jill pulls with 93.3 N in the

Irina18 [472]

Answer:

235.8 N

Explanation:

Given that

Jack

83.5 east

Jill

93.3√2/2 east

93.3√2/2 north

Jane

121√2/2 east

121√2/2 south

From the above listed, we can calculate the total force component on x axis to be

Fx = 83.5 + 93.3√2/2 + 121√2/2

Fx = 83.5 + 65.97 + 85.56

Fx = 235 N (east)

Again, we calculate the total force component on y axis to be

Fy = 93.3√2/2 - 121√2/2

Fy = 65.97 - 85.56

Fy = -19.59 N (south)

Finding the resultant, we have

F = √(Fx²+Fy²)

F = √(235² + (-19.59)²)

F = √55225 + 383.7681

F = √55608.7681

F = 235.8 N

Math Practice: Cart A loaded with blocks (600g) moving left at 0.7m/s hits stationary cart B (200g).

Vika [28.1K]

Answer:

The velocity of cart B after the collision is 1.29 m/s.

Explanation:

We can find the velocity of cart B by conservation of linear momentum:

$p_{i} = p_{f}$

$m_{A}v_{A_{i}} + m_{B}v_{B_{i}} = m_{A}v_{A_{f}} + m_{B}v_{B_{f}}$

Where:

$m_{A}$ is the mass of cart A = 600 g = 0.6 kg

$m_{B}$ is the mass of cart B = 200 g = 0.2 kg

$v_{A_{i}}$ is the inital velocity of cart A = 0.7 m/s

$v_{A_{f}}$ is the final velocity of cart A = 0.27 m/s

$v_{B_{i}}$ is the initial velocity of cart B = 0

$v_{B_{f}}$ is the final velocity of cart B =?

Taking the left direction as the positive horizontal direction:

$0.6 kg*0.7 m/s + 0 = 0.6 kg*0.27 m/s + 0.2 kg*v_{B_{f}}$

$v_{B_{f}} = 1.29 m/s$

Therefore, the velocity of cart B after the collision is 1.29 m/s.

I hope it helps you!
