Option A
The centripetal acceleration is 1.32
<em><u>Solution:</u></em>
From given question,
A cyclist rides in a circle with speed 5 m/s
The circle has a radius of 19 m
To find: Centripetal acceleration
<em><u>The formula for Centripetal acceleration is given as:</u></em>
Where,
= centripetal acceleration
r is the radius and v is the velocity
From given statement,
radius = r = 19 m
velocity = v = 5 m/s
<em><u>Substituting the values in above formula, we get</u></em>
Thus centripetal acceleration is 1.32
Answer:
Step-by-step explanation:
Cosine (cos) is adjacent by hypotenuse.
In any of the 45° angles, 1 is adjacent and √2 is the hypotenuse.
So arrange them to get
