Consider a spherical planet of uniform density rho. The distance from the planet's center to its surface (i. e., the planet's radius) is Rp. An object is located a distance R from the center of the planet, where R
Part A
Find an expression for the magnitude of the acceleration due to gravity, g(R), inside the planet.
Express the acceleration due to gravity in terms of rho, R, π, and G, the universal gravitational constant.
Part B
Rewrite your result for g(R) in terms of gp, the gravitational acceleration at the surface of the planet, times a function of R.
Express your answer in terms of gp, R, and Rp.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
