Explanation:
Answer:
f_D = =3.24 N/m
Explanation:
data given
properties of air

k = 0.0288 W/m.K
WE KNOW THAT
Reynold's number is given as


= 1.941 *10^4
drag coffecient is given as

solving for f_D


Drag coffecient for smooth circular cylinder is 1.1
therefore Drag force is

f_D = =3.24 N/m
As per the question, the distance travelled by bobsled [s] = 100 m
The time taken by the bobsled to travel that distance [t] = 25 s
We are asked to calculate the speed of the bobsled.
The speed of the bobsled is calculated as -




Hence, the correct answer to the question is A. 4 m/s.
Answer:
Unbalanced forces
Explanation:
Unbalanced forces acting on an object can change the object's speed, causing it to speed up or slow down.
