Q. Determine the acceleration of the Moon toward Earth, using values for its mean distance and orbit period from the Terrestrial and Astronomical Data table. Assume a circular orbit. Express the acceleration as a fraction of g. (From the Terrestrial and Astronomical Data table, we find that the sidereal period of the Moon is 27.3 d and that its mean distance from Earth is 3.84 108 m

Q. A particle is traveling in a straight line at a constant speed of 28.0 m/s. Suddenly, a constant force of 15.6 N acts on it, bringing it to a stop in a distance of 66.8 m.

Determine the time it takes for the particle to come to a stop.

What is its mass?
