A plane travels 2.5 KM at an angle of 35 degrees to the ground, then changes direction and travels 5.2 km at an angle of 22 degr
Solnce55 [7]

Answer:

7.7 km 26°

Explanation:

The total x component is:

x = 2.5 cos(35°) + 5.2 cos(22°) = 6.87

The total y component is:

y = 2.5 sin(35°) + 5.2 sin(22°) = 3.38

The magnitude is:

d = √(x² + y²)

d = 7.7 km

The direction is:

θ = atan(y/x)

θ = 26°

The compass uses a pendulous system to improve?
ivanzaharov [21]

The compass is designed and developed to use a pendulous system to improve horizontality.

<h3>What is a compass?</h3>

A compass can be defined as a scientific instrument that contains a magnetized pointer, which is used to show and indicate the following four (4) main cardinal directions:

  • North (N)
  • South (S)
  • West (W)
  • East (E)

Basically, the compass is a scientific instrument that's designed and developed to use a pendulous system to improve horizontality.

A 1,000 kg car is moving at 20 m/s, and slams into a building before coming to a halt.
ale4655 [162]

Hi there!

We can calculate linear momentum using the following:
\large\boxed{p = m v}

p = linear momentum (kgm/s)
m = mass (kg)
v = velocity (m/s)

Calculate:

p = 1000 * 20 = 20000 kg\frac{m}{s}

Now, we can relate force, time, and momentum with the following:
\large\boxed{I = Ft}\\\\

I = Impulse (kgm/s)
F = Force (N)
t = time (s)

Rearrange to solve for force:
F = \frac{I}{t}

The impulse is equal to the change in momentum. Since the car comes to a halt, all of its momentum is lost, so:

I = \Delta p = p_f - p_i = 0 - 20000 = -20000

Solve:
F = \frac{-20000}{0.5} = \boxed{-40000N}

**Negative force since the positive direction is towards the wall, and the negative direction is away from the wall.
