Homework Help: Calculate the speed of the packet

  1. Sep 9, 2008 #1
    1. The problem statement, all variables and given/known data

    While the aircraft is flying horizontally at a speed of 35 m s–1 (600m above the ground), a packet is dropped from it.

    Calculate the speed of the packet when it reaches the ground (include a vector diagram).

    2. Relevant equations

    v=d/t this is the only formula I know when solving speed/velocity
    3. The attempt at a solution

    You know the equations of a parabolic motion?Use H=(u^2sin^2@)/2g to find g,you know H=600 and angle made(@)=90 then find t=(usin@)/g to find t.use v=u+at to find speed,v.It has been long i've done this so you might want to ...
