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.
Gravity x length of slide ,+ unknown factors of slide material
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.
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.
Make the slide steeper Furniture polish on the slide will speed it up.
Use conservation of energy to solve this one. Calculate the gravitational potential energy at the top, and the kinetic energy at the bottom. The difference has been lost to friction, i.e., converted to thermal energy.
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.
Yes, the word 'slide' is both a verb and a noun.
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.
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.
