A gifted child, or a child prodigy.
Yes
Is this a vertical ladder? Another contributor's answer:Providing that the slide is on level ground and that the ladder is vertical then you have the outline of a right angle triangle with an hypotenuse (the slide) of 3 metres and an adjacent angle of 40 degrees. To find the height of the opposite (the ladder) side of the triangle use the trigonometrical sine ratio: sine = opposite/hypotenuse When the ratio is rearranged: opposite = hypotenuse*sine opposite = 3*sine 40 degrees = 1.928362829 metres So the height of the ladder needs to be nearly 2 metres high.
Low friction is slippery high friction has good traction. In the sport of Curling (gliding those heavy granite stones on ice towards a bullseye) one shoe has low friction (to slide on the ice) the other has high friction (to propel the player).
If I give you a 600mL of medicine for 2 adults and 1 child. The child takes 37% of the adult dosage. What are the doses? .....yes, you need algebra. If I got a beaker that is 12 mm high and the mouth opening is 2mm wide, and I ask you to give me a 41.4 cubic mm of a solution, ......yes, you will need trigonometry.
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.
If the child spread themselves evenly, they covered 6.06 kg/m
Gravity x length of slide ,+ unknown factors of slide material
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.
The speed it descends through the outer atmosphere generates high levels of heat.
length of the slide= 47.10 feet
Your supposed to slide, but in order to get it to slide easy you have to hop just high enough to get it to slide correctly
Sandpaper is designed to be a high-friction material. High friction on a slide means less downward force, which means less acceleration and less velocity.
Warm air rises high, Cooler air descends below, Nature's dance unseen.
180 feet high
Schaefer is an alternative spelling and cognate for the German word "Schäfer", meaning shepherd, which itself descends from the Old High German scāphare.
It doesn't change the area of the slide. What it changes is the area in the field of view.
