A 100-kg football player jumps vertically into the air to catch a 0.50-kg football that is thrown essentially horizontally at him at 20 m/s. What is his horizontal speed after catching the ball

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
