Answer:
0
Explanation:
The displacement is zero since it goes in a full circle and ends up where it started.
ΔK = -2334.66J. The kinetic energy loss is -2334.66J.
This is an example of elastic collision which means that the two bodies remain united after the collision, as we know the amount of movement is preserved that is called conservation of momentum. So, we can write the equation as follow:
Where is the initial momentum and is the final momentum.
Substituting the values:
After the collision the bodies are united and move at the speed of 33.33 m/s.
To calculate the kinetic energy lost in the impact we only have to calculate the energy of each body before the impact and compare it with the energy of the whole after the impact.
ΔK =
ΔK =
Substituting the values:
ΔK =
ΔK =
ΔK =
ΔK =
ΔK =
ΔK =
Answer:
The value is
Explanation:
From the question we are told that
The height is h = 2.0 m
The height of the window is
The initial velocity of the rock is
The angle at which it is thrown is
Generally the vertical component of the velocity of the stone is mathematically represented as
=>
Generally the height of the window from the ground is mathematically represented as using kinematic equation as
=>
Here g is negative -9.8 m/s^2 because the direction of the stone is against gravity
So
Solving this quadratic equation using quadratic formula we obtain
t = 0.770 s
Generally the velocity of the stone on the x axis is mathematically represented as
=>
Generally the distance between the person throwing the rock and the window is mathematically represented as
=>
=>
It falls under the fruit category but it is a tropical plant. It is under the Bromeliaceae family.
If you are in this kind of geographical scenery, you must be on a surfing beach in California. The Californian coastline is characterized by a numerous number of beaches that are mainly sandy and features major rivers such as the Sacramento River and the Colorado River.
