24-15=9 m/s slower in 12 seconds. So 9/12 m/s² slower. Therefore the acceleration is -0,75 m/s²
Old temperature = 283 K.
New temp = 323 K.
(323/283) x (325 kPa) = 371 kPa.

According to Newton's law of universal gravitation:
(1)
Where:
is the gravitational force between Earth and Moon
is the Gravitational Constant
is the mass of the Earth
is the mass of the Moon
is the distance between the Earth and Moon
Asuming the orbit of the Moon around the Earth is a circular orbit, the Earth exerts a centripetal force on the moon, which is equal to
:
(2)
Where
is the centripetal acceleration given by:
(3)
Being
the orbital velocity of the moon
