Answer:
Explanation: Its your hairline
hahahahah
Answer:
Explanation:
given,
ω₁ = 120 rpm
1 rpm = 
rad/s
= 12.56 rad/s
α = - 4 rad/s²
diameter of disk = 20 cm
final angular velocity = 0
t = 
t = 
t = 3.14 s.
2) 
= 
= 19. 72 radians
3) total angular distance rotated
x = θ R
x = 19.72 × 0.1 = 1.97 m
x = 2 m
Well, st first we should find <span>initial momentum for the first person represented in the task which definitely must be :
</span>

And then we find the final one :

Then equate them together :
So we can get the velocity, which is

In that way, according to the main rules of <span>conservation of momentum you can easily find the solution for the second person.

The question is incomplete! The complete question along with answer and explanation is provided below.
Question:
A student bikes to school by traveling first 1.00 miles north, then 0.500 miles west and finally 0.200 miles south.
If a bird were to start out from the origin (where the student starts) and fly directly (in a straight line) to the school, what distance db would the bird cover
Given Information:
distance towards north = dn = 1.00 mi
distance towards west = dw = 0.500 mi
distance towards south = ds = 0.200 mi
Required Information:
distance covered by bird = db = ?
Answer:
distance covered by bird = 0.94 miles
Explanation:
As you can see in the attached image, by applying the Pythagoras theorem,
db = √(dn - ds)² + dw²
db = √ (1.0 - 0.20)² + 0.50²
db = √ 0.80² + 0.50²
db = 0.94 miles
Therefore, the bird would cover a distance of 0.94 miles
