Answer:
Radius=15.773 m
Explanation:
Given data
v=29.5 km/h=8.2 m/s
μs=0.435
To find
Radius R
Solution
The acceleration is a centripetal acceleration which is experienced by the bicycle given by

This acceleration is only due to static force which given as

The maximum value of the static force is given as

where
FN is normal force equal to mass*gravity
Therefore when the car is on the verge of sliding

Therefore the minimum radius should be found by the bicycle move without sliding
So

Explanation:
1) Kicking a ball.
2) Capture the ball by hand.
3) Push a car.
In question 2
The second line of equation would be 54 = 108 + 10a
get the rest from that
Since the statement of the problem is to determine if levels of acidity in sea water affect the strength of a sea snail's shell, then the best statement of hypothesis should be:
"<span> if the shells are affected by the level of acidity, then they will be weaker.</span>"
That hypothesis refers directly to the theory being questions in the problem.
