Two football players are initially 20 m apart. The first player (a receiver) runs perpendicularly to the initial line joining the two players at a constant speed of 7.0 m/s. After two seconds, the second player (the quarterback) throws the ball at a hori￾zontal speed of 15 m/s (ignore any vertical motion). In what horizontal direction should the quarterback aim so that the ball reaches the same spot the receiver will be? At what time will the ball be caught?

Two football players are initially 20 m apart. The first player
(a receiver) runs perpendicularly to the initial line joining the
two players at a constant speed of 7.0 m/s. After two seconds,
the second player (the quarterback) throws the ball at a hori￾zontal speed of 15 m/s (ignore any vertical motion). In what
horizontal direction should the quarterback aim so that the
ball reaches the same spot the receiver will be? At what time
will the ball be caught?
