Correct question:
Consider the motion of a 4.00-kg particle that moves with potential energy given by

a) Suppose the particle is moving with a speed of 3.00 m/s when it is located at x = 1.00 m. What is the speed of the object when it is located at x = 5.00 m?
b) What is the magnitude of the force on the 4.00-kg particle when it is located at x = 5.00 m?
Answer:
a) 3.33 m/s
b) 0.016 N
Explanation:
a) given:
V = 3.00 m/s
x1 = 1.00 m
x = 5.00

At x = 1.00 m

= 4J
Kinetic energy = (1/2)mv²

= 18J
Total energy will be =
4J + 18J = 22J
At x = 5

= -0.24J
Kinetic energy =

= 2Vf²
Total energy =
2Vf² - 0.024
Using conservation of energy,
Initial total energy = final total energy
22 = 2Vf² - 0.24
Vf² = (22+0.24) / 2

= 3.33 m/s
b) magnitude of force when x = 5.0m



At x = 5.0 m


= 0.016N

Answer:



Explanation:
M = Mass of Uranus
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Uranus = 25360 km
h = Altitude = 104000 km
= Radius of Miranda = 236 km
m = Mass of Miranda = 
Acceleration due to gravity is given by

The mass of Uranus is 
Acceleration is given by

Miranda's acceleration due to its orbital motion about Uranus is 
On Miranda

Acceleration due to Miranda's gravity at the surface of Miranda is 
No, both the objects will fall towards Uranus. Also, they are not stationary.
The correct answer for the question that is being presented above is this one: "an air mass that formed over land. it is cold and dry." When describing a maritime polar air mass, you might say it formed over land and is cold and dry. It's temperature c<span>an range from around freezing to near 20 degrees Celsius</span>
