A 21.2 kg child descends a slide 3.5 m high and reaches the bottom with a speed of 2.1 ms How much thermal energy due to friction was generated in this process?
The potential energy he lost on the descent = M g H = (21.2) (9.8) (3.5) = 727.16 joulesThe kinetic energy he had at the bottom = 1/2 M V2 = (0.5) (21.2) (2.1)2 = 46.746 joulesThe missing energy = (727.16 - 46.746) = 680.414 joules caused heating of the slide and the kid's pants.
What are some good child safe household starge containers?
Basic plastic containers with plastic lids are lightweight, child safe, and useful for storage. These containers can be found at your local Target or Walmart stores.

What is in the slide of the mitochondria?
slide? your obviously doing something for cyberschool and you need to use the slide viewer =P ^ Retard... Slide referring to the slide under the microscope. And the answer would be the inner and outermembrane.
A 21.2 kg child descends a slide 3.5 m high and reaches the bottom with a speed?
The answer depends on the incline (slope) of the slide. And, if you want a more realistic answer, a measure of the friction between the child and the slide.
A 21.2 kg child descends a slide 3.5 m high and reaches the bottom with a speed of 2.1 ms How?
Gravity x length of slide ,+ unknown factors of slide material
Is a Little Tykes slide safe?
Yes, the Little Tikes slide is safe. As long as children are supervised, and are not left alone, the slide is perfectly fun and safe for children.
When does a child on a slide have its maximum kinetic energy?
If the slide has no friction, then at the bottom of the slide. If it does then it's when the child is going the fastest.
How can you slide down the slide faster?
Make the slide steeper Furniture polish on the slide will speed it up.
Are cheap treadmills safe to use by children?
It is impossible to say if cheap treadmills are safe to be used by children, it depends upon the treadmill. If you or a child is using an electronic treadmill which can alternate speed, you must set it to a speed you/they can handle else it wont be safe for anyone.
What is the coefficient of friction between a playground slide and a child if the child accelerates down the slide at 1.16 meters per second squared and the slide is inclined 31 degrees?
china
When you apply slide transitions you can control the what?
speed
How safe is the little tikes slide?
The little tikes slide is safe as long as proper supervision by an adult is provided during the use of the slide. It is also important to make sure you follow the age guidelines for proper use.
Is friction useful when you are on a slide?
if there was no friction on a slide, you would gain speed and slide off and depending on the slide (such as a water slide) kill yourself. too much friction makes it boring.
Is softball safe at all?
No. Softball is not safe because if you slide you can sprang your ankle the ball is to hard and what if you have metal cleats and you slide into the catcher that could damage the catchers leg.
You may be cited for driving at the posted speed limit?
If the posted speed is not safe at that time
