Help Jack!!
Some Jack's physics and see how it helps him escape the flying Duchman :P
Q.1 Jack is on the top of a mast(10 m high see level) of his Black Pearl and sees the flying Duchman (point sized :P) at a distance of 10√3 m. With what minimum speed he must shoot his riffle to hit the Flying Duchman?
Contd... in next post Jack's second adventure...
33Adventure 2.
Jack's Ship is caught in a storm while escaping from the Flying Duchman. Black pearl(his ship.. his :P) has a velocity of 3 m/s in west to east direction and due to storm his ship gets an acceleration of 2m/s2 in south north direction.. Find radius of curvature of the path traced by Black pearl as a function of time.. assume t=0 at the instant shown..
11did u think the question out for to suit ur name
or u changed ur name to suit the question??
33Don't forget to help Captain sparrow..
Adventure 1... is a good question which will take ur little time if u proceed conventionally taking u and θ and then writing equations and differentiating to get min u..
But if U plan doing this that way don't do it as u can surely do it that way so why waste ur time in this if u have some badmasi in ur mind then try it and may be u can get 3 line soln..
:)
11jack sparrow is a proclaimed hero and he can save himself
NOT GOING TO HELP HIM
:P
33Captain!! the flying Duchman is approaching near.. shoot..
Jack: No i will shoot with minimum velocity...

11Not even can the great Jack Sparrow shoot a point sized target. You don't have the man for this job - RAJNIKANTH or VIJAYKANTH.
For tales of RAJNIKANTH's and VIJAYKANTH's greatness see http://targetiit.com/iit_jee_articles/why_newton_committed_suicide_63_an_interesting_sto_75.html

i thought abt the first
i know ths is not the smallest method
but simpler than the longest method
considering projection angle as theta+30
and considering AB and a line ppr to it as the axes
we get time of flight directly
easier to minimize velocity
1arey yar...jack sparrow is such a skillful captain he cld himself find a way out...
n considering black pearl..its a g8 ship to go through nyhtng so CHILL....question chodo movie dekho!!hahaha
