Can someone please help me with the physics/math problems. I dont understand how to do them.?
1) -a & b- toss up a coin and watch what happens. Gravity happens. So in air its velocity constantly changes. But the acceleration stays the same because gravity's pull neither increases nor decrease 2) use the equation X= VoT+ (1/2)AT^2 where X is distance, A is acceleration of gravity, Vo is initial velocity, and T is time. A is always -9.80 m/s^2, Vo is zero because pebbles falls from rest, and time is 1.5 seconds. Plug it into the equation and u get X=(0)(1.5)+(1/2)(-9.80)(1.5^2)= -11.025 meters [negative because its going downwards] 3) As mentioned gravity's pull remains constant throughout and if u observe the coin toss, at the peak, its not going up nor is it going down, so the velocity is zero always the maximum altitude and acceleration -9.80 m/s^2 4) ^see above, acceleration remains constant : -9.80 m/s^2 5) ^once again see above. I am not sure if you know this or not but the plus minus signs indicate the direction of the gymnist (plus meaning she is going up and minus meaning going down) and when u draw this out u should be able to see the one with +4.0 m/s one has a parabolic curve. Meaning, that when she is going down, her velocity at the height at which she started from is going to be opposite to her initial velocity. Meaning, going downwards from the bar height, her velocity is -4.0 m/s. I am sure you know that her velocity increases at the same rate going downwards. Therefore one with +4.0 m/s will have more velocity than the one with -3.0 m/s. Just make sure you typed the question correctly, it seems odd that you would be asked the same question with acceleration over and over again.
"Throwing" toddler onto couch?
My 2 year old nephew LOVES to be lightly tossed from 1-2 feet in the air onto the couch. he's a boy, so he loves those "thrilling" activities :). Is this okay? I don't want to hurt his neck or bones. I support his head and am sure he lands gently [he always gets up laughing], but I don't want to hurt him. Advice?
Is throwing a cat in the air or on the floor dangerous to the cat?
i do lol.....well i kinda toss him not exactly throw him, my cats always trying to bite me too sometimes i make him do back flips when i play with him and he does land safely when i do it, i mean think about it, cats always jump from places anyway so i think he will be ok just dont do it too rough, that might be dangerous
Throwing baby's up in the air?
No, you are right. That is a very real fear and also, depending on the age of the baby, the force of being tossed and caught can cause injury, even shaken baby syndrome. I would not let anyone do that with my baby. You can make a little joke about it to the uncle - like, oh, I know I am just over protective but I can't stand seeing that with little Jimmy. When he is older you can roughhouse... something like that.
1 year old has visible finger mark bruises on her leg?
on her lower leg there is visible finger mark (3 fingers and a thumb) bruises, my boyfriend said it may have been him when he was changing her diaper, i am thinking.. how hard did he have to grab her to cause these bruises? he rarely changes her diaper ( he works) im stay at home mom, so no one else cares for my daughter. I know he probably didnt do it on purpose.. just doesnt know his own grip strength?, should i not let him change her diapers anymore? should i watch him? i dont want him to feel like a child abuser but i need to see what he is doing wrong and how i can correct him. I know he will be offended if i do this in an obvious way.
Is it bad to throw my dog in the air like a baby?
It’s not a good idea.First, it will scare the dog and may cause him/her to be afraid to be picked up for fear of being tossed in the air. Second, it could easily cause physical harm. When you throw him, he’s going to twist his body around and tense up trying to land on his feet (remember he doesn’t understand that you’re going to catch him). Then there’s the problem (from the twisting) that you’re not going to be able to pick the spot on his body that you catch him if your hand hits the wrong place you could do severe damage,(if you hit his neck area wrong you could easily break his neck).I have, however, taught a dog to jump into my arms. This worked well because he felt in control of his leap/toss and didn’t tense up. I started with him jumping into my arms from the ground and built trust that I wouldn’t drop him. Also, I never forced him to jump if he wasn’t willing to do it. He picked the heights that he jumped from. His limit was to jump to me from a chair or the car.I have a boxer/mastiff mix that I’m hoping will jump to me while I’m in the pool. Since he’s already 100 lbs at 8 1/2 months I don’t think I want to catch him without the water to help me. It’s cool and fun to have a pet that does things that other peoples can’t do, but in the end it’s always about what’s best for the animal.
