I believe the coma is formed from the dust and gas from a comet.
Hope this helps!! :)
Answer:
Explanation:
Gravitational potential energy is found using the following formula.
where <em>m</em> is the mass, <em>g</em> is the gravitational acceleration, and <em>h</em> is the height.
1. Define Variables
We know the anvil's mass is 115 kilograms and it's 85.0 meters above the coyote. Assuming this is on Earth, the acceleration due to gravity is 9.8 m/s²
2. Calculate Potential Energy
Substitute the values into the formula.
Multiply the first two numbers together.
Multiply again.
- 1 kilogram square meter per square second is equal to Joule.
- Therefore, our answer of 95795 kg*m²/s² is equal to 95795 J
The anvil has <u>95,795 Joules </u>of gravitational potential energy.
Answer:
22.3Ns
Explanation:
Hi!
To solve this exercise follow the steps below.
1. Find the weight of the stone by multiplying the gravity (9.8m / s ^ 2) by the mass.
W=mg
m=mass=2.5kg
g=gravity=9.8m / s ^ 2
W=(2.5)(9.8)=25.5N
2. Find the time it takes for the stone to touch the ground using the kinematic equation for constant acceleration.
Vf=Vo+a.t
y= VoT+\frac{1}{2}gt^{2}
Where
Vo = Initial speed
=0
T = time
g=gravity=9.8m/s^2
Y= height= 3.75m
solving for time
3. For a constant force such as weight, the impulse is calculated as the product between force and time.
I=wt
I=(25.5N)(0.87S)=22.3Ns
