What forces do you want to consider? There is not really a generic notion of "interacting balls"If the balls are attached by a spring, your Lagrangian is:$$L = frac12m_1dot vec x_1^2 frac12m_2dot vec x_2^2 frac12 -kleft(vec x_1 - vec x_2
ight)^2$$If the are interacting through gravity, it is:$$L = frac12m_1dot vec x_1^2 frac12m_2dot vec x_2^2 fracGm_1m_2left|vec x_1 - vec x_2
ight|$$There are many other choices. It ultimately depends on what effect you are studying
1. Balls thrown up in Physics?
Physics? ball thrown upward vertically, optimal suited? a ball is thrown upward with an initial speed of 29.4 m/s. What optimal suited does the ball attain? even as an merchandise is thrown upward, it decelerates 9.8 m/s each and every 2d, till its speed = 0 m/s. right this moment the article is at its maximum aspect. Then it quickens downward at 9.8 m/s each and every 2d. If the starting up aspect and end aspect are a similar, the path is symmetrical. the article strikes down a similar distance it moved up. the staggering speed on the top of the downward holiday equals the initial speed of the upward holiday. The time to achieve the flow as a lot because the utmost aspect is an similar because the time to fall decrease backtrack to the starting up aspect. the fee of a ball with initial vertical speed of 29. 4 m/s will shrink 9. 8 m/s each and every 2d till the vertical speed = 0 m/s vf = vi a*t vf = 0 vi = 29.4 a = -9.8 0 = 29.4 (-9.8 * t) t = 3 seconds because the fee is lowering at a consistent fee, the gap the ball strikes equals its undemanding speed circumstances the time. undemanding speed = (initial speed very last speed) 2 undemanding speed = (29. 4 0) 2 = 14. 7 m/s Time = 3 seconds Distance = 14. 7 m/s * 3 s = 40 4. a million m is it 44m or 88 m (40 4) are you able to employ d=vt NO, because the fee became no longer 29.4 m/s each and every of the time!! v many times ability consistent speed. even as an merchandise is transferring upward, its speed is lowering because of the attractive stress between the article and the earth. are you able to come across t? convinced, by ability of dividing the initial speed by ability of the deceleration
2. Shaved my balls now they itch unbelievably?
Get your girlfriend to itch them for you
3. How do you clean tennis balls?
Wash them in a bucket of soapy water Let them soak for about 30 minutes, or longer if they are extra crusty. Scrub the tennis balls with a rag or sponge to get the extra dirty spots clean. Rinse with warm water, then rub with a towel to dry. Regarding this, why put a tennis ball in the washing machine? When you are washing anything down-filled, such as a comforter or bed pillows, adding a few new, clean tennis balls to the dryer will help fluff them up. If you are ever pulled a freshly-washed pillow out of the dryer to find it had become lumpy and misshapen, the tennis ball trick can prevent that. Beside above, how do tennis balls help in dryer? Adding a few tennis balls to the dryer helps fluff up towels and sheets, and decreases lumping in items like comforters, down jackets, and pillows. The tennis balls bouncing around in the dryer knock out the lumps you would otherwise need to pat out by hand. Bonus: It can also reduce drying time (and energy spent). People also ask, what can I put in the dryer instead of tennis balls? Instead of using a tennis ball, other objects can produce the same results. Tie a couple of T-shirts into balls and put them in the dryer with a single pillow. Add in a single clean shoe with multiple pillows. Small stuffed animals without any plastic parts can fluff the pillows and keep the dryer quiet. Heating it can affect the gas inside of the ball though. Finally, soaking the ball in water will decrease bouncing height because the water which is absorbed by the "fur" will move around and absorb kinetic energy when the ball hits the ground, leaving less energy to help the ball bounce back up.
