Homework Statement
One stellar mass is defined as the mass of our sun (1Ms = 1.99 x 1030 kg). ONe astronomical unit is defined as the length of Earth's semi-major axis (1AU = 1.49 x 1011 m). The star Epsilon Eridani in the constellation Eridanus has a planet (discovered in 2000) orbiting it...
d certainly is 0.
The question is exactly as I have above.
My impression was that this question resembled the vertical component of a projectile motion question. Up and back down, 0 displacement.
Kinematics, given only "vi" "vf" and "d"
Homework Statement
I have a hunch this problem is impossible with the given information.
Using the given information, solve for a and t.
vi = 7.185m/s
vf = -7.185m/s
a = ?
d = 0m
t = ?
