The motion of a human body through space can be precisely modeled as the motion

Question

The motion of a human body through space can be precisely modeled as the motion of a particle at the body's center of mass. The components of the displacement of an athlete's center of mass from the beginning to the end of a certain jump are described by the two equations below, where t is the time at which the athlete lands after taking off at time t = 0.

xf =0 + (10.5 m/s)(cos 20.1

Explanation / Answer

Taking the equation:
0.369 m = 0.812 m + (11.1 m/s)(sin 20.3
