An infant's toy has a 120g wooden animal hanging from a spring. If pulled down gently, the animal oscillates up and down with a period of 0.50s . His older sister pulls the spring a bit more than intended. She pulls the animal 30cm below its equilibrium position, then lets go. The animal flies upward and detaches from the spring right at the animal's equilibrium position.
If the animal does not hit anything on the way up, how far above its equilibrium position will it go?
h=_____cm
Answer
By ω = √k/m
=>(0.50)^2 = k/0.12
=>k = 0.03 N/m
By the law of energy conservation:-
=>KE(max) = PE(spring)max
=>1/2mv^2 = 1/2kx^2
=>1/2 x 0.12 x v^2 = 1/2 x 0.03 x (0.3)^2
=>v = √0.0225
=>v = 0.15 m/s
=>By v^2 = u^2 -2gh
=>0 = (0.15) - 2 x 9.8 x h
=>h = 0.001148m
=>h ≈ 0.12 cm

Answer
The Best Teething Toys
By Miebeth Bustillo-Booth, ChildTrek Founder
Natural & Wood Teethers
The best teething toys are made of natural materials like wood. Wood is naturally anti-bacterial. (That’s why there are wooden cutting boards.) So it is self-cleaning. Wood is hard and will help ease teeth in. But not all wood toys are ideal. The best wooden teething toys are either unfinished or lightly finished with beeswax, water-based stains, or other non-toxic paints. It’s best to gain the manufacturer statements to this effect. At ChildTrek, only toys that have met or exceeded safety standards are available.
Great Teething Toys
Grabbing Toy Giraffe with Wooden Teething Ring by Kathe KruseConsider the Infant Grabbing Toy Mah or Giraffe by Kathe Kruse. They are made out of non-porous beech wood, lightly finished with beeswax, and made using non-toxic dyes. There are no harmful chemicals to leach out while your baby gnaws on the hard wood. The wooden ring is extra large for easy handling by small hands. The lamb and the giraffe can be removed for machine or hand wash. And they are completely adorable!
The Grabbing Star Red or Blue also by Kathe Kruse has a wooden teething ring and interesting textures for early learning stimulation. A special feature is a velcro loop at one of the star ends so that it can be fastened as a stroller toy. This achieves a couple of things: the teether is always nearby and it doubles as a grabbing toy. Smart!
Girali Rattle by SelectaThe Girali Rattle by Selecta, aside from being a practical teething toy, is uniquely beautiful. It is made of native woods from Germany and finished with beeswax and non-toxic paints - completely safe for your baby.
Also, it’s hard to beat the Cherry Rattle by Camden Rose. It is lightly finished with beeswax. Its contoured design makes for interesting tactile stimulation. Its gentle rattle is soothing. As a teether - it is naturally hard to facilitate teething. Watch as your baby gnaws on this beautiful toy for hours.
Cold and Soothing
Organic Vegetabe Teethers by Under the NileOne of my personal favorites for the summer are the organic teethers by miYim and Under the Nile. Take the Bunny, Elephant, or Bear teether. Dampen, not soak it. Put it in the freezer. Then let your baby gnaw on this cool toy to help soothe tender gums. Do the same for the Fruits or the Vegetables by Under the Nile. Besides gently soothing for your baby, you are teaching your baby to “eat” his or her fruits and veggies!
Vary Teethers
It’s best to keep a few different teethers around that have varying textures and hardness. Some teeth come in easier than others. The molars, for example, are especially hard on infants.
