An astronaut throws a rock at 12 m/s at an angle of 25° above horizontal from a height of 3.25 m above the surface. How far horizontally does the rock travel before hitting the surface of Pluto?
Pluto has a mass of 1.27 E22 kg
And a radius of 1.14E6 m
(Projectile equations )
d=vo(t) + .5a(t^2)
The Attempt at a Solution
I know how to solve projectiles , except how do I find gravitational acceleration for Pluto ? [/B]
