Homework Statement
The motion of a human body through space can be modeled as the motion of a particle at the body's center of mass. The components of the position of an athlete's center of mass from the beginning to the end of a certain jump are described by the following two equations, where t is the time at which the athlete lands after taking off at t = 0.
xf = 0 + (10.6 m/s)(cos 18.5°)t
0.230 m = 0.600 m + 0 + (10.6 m/s)(sin 18.5°)t - (9.80 m/s2)t2
Identify his vector position.
Homework Equations
The Attempt at a Solution
I tried to solve for t in the second equation and got a value of 0.783s, after which I put this value into the first equation and solve for x and got 7.87m for the i direction. I did not really know what to put in for the displacement along the y-axis.
