Homework Statement
Here's a similar problem to the one in my book (I don't want to post the one in my book as I don't want to cheat):
The gravitational acceleration on Mars is 3.719[m/s^2].
The gravitational acceleration on Earth (excluding air friction and other places) is 9.81.
the initial velicty is this given in polar coordinates: 30<45o
How far will a ball go on Earth compared to on Mars? Use range calculations
Homework Equations
I want to say this is it:
R = vi2/g * sin2(theta) [/B]
The Attempt at a Solution
I did the following:
convert polar coordinates to rectangle coordinates:
x = 22cos(90)
y = 22sin(90)
x = 0
y = 22
R = (0,22)^2/9.81 * sin2(theta)
R = (0,22)^2/3.71 * sin2(theta)
That's all I got and that doesn't seem right.
