Projectile Motion Challenge Problem

  1. Jul 10, 2014 #1
    Mr. Smith’s dog Rosie takes a flying leap off his bed. The bed is 1m high, and Rosie leaves with a muzzle velocity of 5 m/s [40° above the horizontal].
    Sometime after Rosie leaves the bed, Mr. Smith (who is 5m away from the bed) throws a doggie treat to Rosie from ground level with a muzzle velocity of 7 m/s [20° above the horizontal].
    How many seconds does Mr. Smith need to wait after Rosie leaves the bed, to throw the treat such that Rosie catches the treat in mid-air on her way down?



    First I tried to figure out final velocity & vertical distance for rosie ......which I got as 0.32s & 0.526m respectively.
    But I am really not getting an idea about how to proceed further ...Please help me with this.

    Don't figure anything out until you've figured out your gameplan.

    What does it take for Rosie to catch the treat on her way down?
