A uniform, 4.5 kg, square, solid wooden gate 2.0 m on each side hangs vertically from a frictionless pivot at the center of its

upper edge. A 1.3 kg raven flying horizontally at 5.0 m/s flies into this door at its center and bounces back at 2.0 m/s in the opposite direction.
Required:
a. What is the angular speed of the gate just after it is struck by the unfortunate raven?
b. During the collision, why is the angular momentum conserved but not the linear momentum?

2. An airplane travels 335
Mama L [17]

Answer: The answer is 716.8 km/hr

Explanation:

The main idea here is the convert the given units to km and hr. Here's the conversion factors.

1mi= 1.6km

1hr= 60min

We have to multiply 335miles by 1.60km/mi in order to get the answer in km then again we have to multiply 45 minutes by 1hr/60min in order to get the answer in hr.

The last step is to calculate the speed using the formula : v=d/t

=537.6km/0.75hr

=716.8km/hr

Wewaii [24]

Answer:

The speed of planes is 419.31 miles per hours

Explanation:

Given that

\dfrac{dS}{dt}=-400\ miles/hr

S= 10 miles

And we have to find \dfrac{dx}{dt}.

From triangle ABC

AC^2=AB^2+BC^2

S^2=x^2+3^2}

by differentiating with respect to time t

2S\dfrac{dS}{dt}=2x\dfrac{dx}{dt}

S\dfrac{dS}{dt}=x\dfrac{dx}{dt}

Now when S=10 miles then

10^2=x^2+3^2}

x= 9.53 miles

So

S\dfrac{dS}{dt}=x\dfrac{dx}{dt}

10\times (-400)=9.53\times \dfrac{dx}{dt}

\dfrac{dx}{dt}=-419.31\ miles/hr

So the speed of planes is 419.31 miles per hours
