Find the velocity and acceleration vectors in terms of up and up. do r = a(1 - sin 0) and dt =7, where a is a constant V= Up + FE Up + UOA moon is in orbit around a planet. The moon's orbit has a semimajor axis of 4.4 x10" m and has an orbital period of 1.569 days. Use these data to estimate the mass of the planet. . . . Express the mass of the planet, M, in terms of the orbital period T, the length a of the orbit's semimajor axis, and the universal gravitation constant G. M = 0 (Use integers or fractions for any numbers in the expression.) The mass of the planet is approximately |kg. (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to three decimal places as needed.)
