In a football game, a 90 kg receiver leaps straight up in the air to catch the 0.42 kg ball the quarterback threw to him at a vigorous 21 m/s, catching the ball at the highest point in his jump. right after catching the ball, how fast is the receiver moving?

To solve this problem it is necessary to apply the equations related to the conservation of momentum. Mathematically this can be expressed as

Where,

= Mass of each object

= Initial velocity of each object

= Final Velocity

Since the receiver's body is static for the initial velocity we have that the equation would become

Therefore the velocity right after catching the ball is 0.0975m/s
