The 1992 world speed record for a bicycle (human-powered vehicle) was set by Chris Huber. His time through the measured 200 m st

aleksklad [387]

Answer:

Speed of Chris Huber = 30.726 m/s

Time taken by Sam = 5.55 s

Step-by-step explanation:

Given:

Distance = 200 m

Time taken by Chris Huber = 6.509 s

Now,

Speed of Chris Huber = $\frac{\textup{Distance}}{\textup{Time}}$

Speed of Chris Huber = $\frac{\textup{200 m}}{\textup{6.509 s}}$

Speed of Chris Huber = 30.726 m/s

Speed of Sam = Speed of Chris Huber + 19.0 km/h

Now,

1 km/hr = 0.277778 m/s

thus,

19.0 km/h = 19.0 × 0.27 = 5.278 m/s

thus,

Speed of Sam = 30.726 + 5.278 = 36.004 m/s

therefore,

Time taken by Sam = $\frac{\textup{Distance}}{\textup{Speed}}$

Time taken by Sam = $\frac{\textup{200}}{\textup{36.004}}$ = 5.55 s

Find the length of an arc made by a 180-degree central angle in a circle with a 10ft radius

mixas84 [53]

Answer:

the length of an arc = 10π ft.

Step-by-step explanation:

The length of an arc with angle Θ and radius r will be equal r * Θ

note the angle must be in radian

Given: Θ = 180° = π and radius = r = 10 ft.

<u>So, the length of the arc = π * 10 = 10π ft.</u>
