Homework Statement
An astronaut on a strange planet finds that she can jump a maximum horizontal distance of 10.0 m if her initial speed is 2.40 m/s.
Homework Equations
What is the free-fall acceleration on the planet? (Ignore air resistance.)
The Attempt at a Solution
So in order to this I used both position functions in the x and y directions to get. x_f= 2.40(cos45)t and y_f= 2.40(sin45)t-(1/2)gt^2. i solved for t to get the time which is t= 5.89 seconds. and then now i know i have to find y_f so then i can plug it in and find g! but how am i supposed to find y_f without a equation that is also dependent on g?
