Answer:
<u>Given </u><u>information:</u><u>-</u>
- Radius of the circular track is <u>636 m</u>
- The time elapsed in the journey is <u>1.5 min or 90 s</u>
- The distance traveled by the cyclist is semi circumference of the circle = <u>πr</u>
The displacement of the cyclist will be shortest distance from his initial to final positions which is nothing but diameter of the circle = 2r
<u>We know that,</u>
- Speed of the cyclist is 22.18 m/s
- <u>Velocity of the cyclist</u> is 14.13 m/s
Thank You :)

<span>Plasma Basics. Plasmas are a lot like gases, but the atoms are different, because they are made up of free electrons and ions of an element such as neon (Ne). You don't find naturally occurring plasmas too often when you walk around. They aren't things that happen regularly on Earth.</span>
Answer:
Because you need to have that momentum to decease over a little bit of time because if it doesn't have room to move backward, that force isn't going to reduce and it will hurt very badly.
Answer:
θ = 26.6°
Explanation:
Formula for maximum height is;
h = u²sin²θ/2g
We are told maximum height is 25 m, thus;
u²sin²θ/2g = 25 - - - - (eq 1)
Formula for horizontal range is;
R = u²sin2θ/g
In Mathematics, sin2θ = 2sinθcosθ
So; R = 2u²sinθcosθ/g
R = 2u²sinθcosθ/g
We are given Horizontal range = 200 m.
Thus;
2u²sinθcosθ/g = 200 - - - - (eq 2)
Divide eq 1 by eq 2 to get;
200/25 = 4cosθ/sinθ
8 = 4cosθ/sinθ
4/8 = sinθ/cosθ
0.5 = tan θ
θ = tan^(-1) 0.5
θ = 26.6°
