Now this is an awesome question.
A cat is running in a straight line at a constant speed u.
2.) Find the final separation between the 2 animals, if d = 10 m; and, u = v = 3 m/s.
P.S.: To check your answer at the judge, use this syntax without the inverted commas(ie, if your answer is 6.32 and 5): "6.32,5.00"

A cat is running in a straight line at a constant speed u.
Now a dog sees the cat when their line of separation(=d) is perpendicular to the line of motion of the cat and starts running after it at a constant speed v, such that it's always headed towards the cat.
1.) Find the total time taken by the dog to catch the cat if v = 3 m/s; u = 2 m/s; and, d = 10 m.
2.) Find the final separation between the 2 animals, if d = 10 m; and, u = v = 3 m/s.

Not very confident.Tried doing it without using calculas and got t=10/root(5)
ReplyDeletet=2root(5) and final separation is 10 m.
ReplyDeleteall wrong..
ReplyDelete(1). 3.33seconds
ReplyDelete(2). 3.33m
ReplyDeletetime 2root5 ni h kya??
ReplyDeletestill wrong!
