Answer: A) 0.19 kg.m/s South just answered it right on Apex!
Explanation:
Answer:
29274.93096 m/s
Explanation:
= Distance at perihelion =
= Distance at aphelion =
= Velocity at perihelion =
= Velocity at aphelion
m = Mass of the Earth = 5.98 × 10²⁴ kg
M = Mass of Sun =
Here, the angular momentum is conserved
Earth's orbital speed at aphelion is 29274.93096 m/s
Kinetic energy is given by
Kinetic energy at perihelion is
Potential energy is given by
Potential energy at perihelion is
Kinetic energy at aphelion is
Potential energy is given by
Potential energy at aphelion is
Total mechanical energy: D) 2800 J
Explanation:
The total mechanical energy of an object is given by
where:
is the kinetic energy of the object, which is the energy possessed by the object due to its motion, where
m = mass of the object
v = speed
And
is the gravitational potential energy of the object, the energy possessed by the object due to its location, where
is the acceleration due to gravity
h is the height of the object above the ground
For the body in this problem, we have:
m = 4.0 kg
v = 20 m/s
h = 50 m
Substituting, we find its total energy:
