Welcome to the math problem thread, I'm Mike. I'll post a new math problem in this thread every day and if you are the first to answer it correctly with proper work, you get reputation added. After I week I may have a prize for the overall winner. Here's today's (May 8th) Problem: We'll start off with an easy one - Imagine launching a water balloon with a slingshot from an initial height of 2 meters. A target is 68 meters away. Assuming it was launched at a perfect 45 degree angle, answer the following: a. What must the initial velocity of the balloon be in order to hit the target? and b. How long will the balloon be in the air?
Homework? lol It's just a little test to see how the DP community is doing in the math department. Sure you could call it physics but you need very little physics, most of it is algebraic. EDIT: Mightyb, assume none.. none, none, none, and none.
So why the proper working out, go on admit it, your sat at home with your satchel and short pants on, polishing the apple for the teacher, aren't you?
Nobody can solve a problem like this? Sad.. I thought DP Posters were at least smarter than rocks.. pebbles perhaps..
THIS IS Physics!!!! Why don't you just use the famous five equation to solve this? You have height, (Distance for Y) and 68 metres (distance for X). You know the acceleration of the earth right? 9.8 m/s^2 AND you have the angel, which you can use the pythagoras theory to find other missing properties?
dp is a webmasters forum, and not physica and maths forum! the only thing i can say is you are on a wrong place! try the allexperts.com it can help you, now that is a good answer
YEah phics and maths just sucks.. i was very weak when i was in it.... But now i can answer all the Accountancy related stuff lol
hey dude keep them coming, I'm noting all the problems Bookmarked this thread These Problems will help me in CET (Common Entrance Test) next year
To put it bluntly, your question cannot be answered because you have not assigned a weight/mass to the balloon. There will also be variances because the balloon cannot follow a perfect 45* angle. Naturally, as gravity pulls down, the angle will drift into a more skewed parabolic shape. Something like /| whereas the baloon drops at a steeper angle than it ascended. The only way to counter this and achieve a perfect parabolic path is to assume a more constant velocity.
