The train is moving at a speed of 50 miles / hour ... On the way, he bumps into a light balloon .. Question: How fast the ball will fly away?
it will start at 50 mile per hour, but will slow almost instantly. I can't answer it numerically, but it wouldn't take long, as the balloon has almost no mass and a lot of resistance, so it slows fast.
I don't think the train will affect the balloon if it is made of light... Unless you meant something else by "light balloon".
Your answers show that you never studied physics ... ------------------------------- The answer is simple: The ball will fly away from the forward speed = 2 * 50 = 100 miles / hour In the USSR this task asked students 14 years ... ==================== How to decide? - Movement - a relatively; - Go to the reference system, which is connected with the train; - In this system the ball is moving at a speed of 100 miles / hour - After the impact, the ball should bounce with the same speed .. 100 miles / hour ----------------------------------------- Now we go in the frame of reference of the earth ... How fast will fly ball? Answer: 100 miles / hour, in front of the train, which travels 50 miles / hour ============================== That's all... Teach Physics!
Okay, first of all, either there was something lost in translation or your explanation is wrong. I could explain how come, but you probably won't understand me as your grip of physics or english is rather loose.
Your solution ignores physics, and the parameters you had in your original post. The original post said a light balloon, not a ball. A light balloon has almost no inertia, and will be effected by the wind. In addition, in the original problem, nothing about direction was posted. You never mentioned that the balloon was being bumped forwards, backwards or sideways. The way you wrote your original problem was extremely flawed, making it impossible to answer.
Good... It is possible that I incorrectly said the question task. I apologize... I will try again: -------------------------------- 1. A train traveling at 50 miles / hour 2. The train crashed into a ball ... 3. Naturally, the mass of the sphere is small compared with the mass of the train; 4. The balloon flies forward ... 5. strike absolutely elastic. 6. An inertial reference system. These conditions enough !!!! ------------------------------------------------ Question: - How fast will fly off the ball? =============================== Man, this is a classic problem of "Mechanics section, the relativity of motion" .... physics textbook for students 17-years USSR ====================================== Decision: 1. The laws of classical physics, the mechanics are the same for all inertial reference systems (that is, for those who are moving at a constant speed) 2. To solve the problem, it is more convenient to go to the reference frame associated with the train ... - In this system moves toward the reference ball train at speeds of 50 miles / hour - Kick perfectly elastic. - Hence, in the reference frame associated with the train, the ball will fly away from the train at a speed of 50 miles / hour ... -------------------------------------------------- -------- 3. Now go to the frame of reference associated with the earth ... - The train is moving at a speed of 50 miles / hour, then add the speed of the ball relative to the train - it is 50 miles / hour, so get a definitive answer: The ball will move at a speed of 100 miles / hour ... ========================================= That's all.... Teach Physics!
I am one of your messages will not understand anything .. Neither physics, English or Russian ... One sh...ttttttt...
You didn't give enough information to solve it. What's the mass of the balloon? In English, balloon refers to a very thin latex or mylar layer that encloses a gas: This is a balloon: In the atmosphere, not in a vacuum, there is no way a balloon can go 100 miles per hour. If you're talking ball, again, you need mass.
You failed to specify relevant variables. Such as initial velocity and mass of balloon, and mass of train. The question cannot be answered.
