To solve this problem we will find the net speed, through the two components given. The vertical component will be found through the energy conservation theorem. Finally with speed we will find the momentum as a function of mass and speed. Given the weight we will divide it by the acceleration to find that mass.
The x component is given as
For conservation of energy the vertical component of velocity would be
Here,
m = Mass
g = Gravitational acceleration
h = Height
Replacing we have that the vertical velocity is
The magnitude of this velocity would be
Finally the momentum of the bale would be
Therefore the momentum of the bale the moment it strikes the ground is
Answer:
<em>The correct option is 1. 720 m</em>
Explanation:
<u>Projectile Motion</u>
When an object is launched in free air (no friction) with an initial speed vo at an angle , it describes a curve which has two components: one in the horizontal direction and the other in the vertical direction. The data provided gives us the initial conditions of the survival package's launch.
The initial velocity has these components in the x and y coordinates respectively:
And we know the plane has an altitude of 600 m, so the package will reach ground level when:
The vertical distance traveled is given by:
We'll set up an equation to find the time when the package lands
Solving for t, we find only one positive solution:
The horizontal distance is:
The correct option is 1. 720 m
Answer: The train traveled 210 miles in 6 seconds of time duration.
Explanation:
The initial velocity of the train,u = 50 mile/s
Acceleration of the train ,a =
Duration of time ,t = 6 seconds
Using second equation of motion :
The train traveled 210 miles in 6 seconds of time duration.
Answer:
The last question is one Liter (sorry that is the only question I know for now).
Explanation:
Mainly because 1000cm is the same volume and area for an answer from this equation which is the block of wood.
Sorry that that was the only answer I knew :(
I'll see what else I can find and I'll edit this question later and write the rest of the answers-or any of them that I will know later on :)
I hope this answer helps :)
