Answer:
1.78 rad/s
1.70344 rad/s
Explanation:
v = Velocity = 0.8 m/s
m = Mass of person = 60 kg
 = Distance between center of mass of person and pole = 0.45 m
 = Distance between center of mass of person and pole = 0.45 m
 = New distance between center of mass of person and pole = 0.46 m
 = New distance between center of mass of person and pole = 0.46 m
I = Moment of inertia
Angular speed is given by

The angular speed is 1.78 rad/s
In this system the angular momentum is conserved

The new angular speed is 1.70344 rad/s
 
        
             
        
        
        
When cattle are processed, the most likely use for the animals' skin is in 
the production of Leather.
<h3 /><h3>Animals used for Leather production</h3>
The commonly used animals in leather production is however cattle and 
they amount for a large percentage of leather present today. They also 
involve various techniques such as tanning and crusting to ensure 
conversion to leather.

Answer:
  a =( -0.32 i ^ - 2,697 j ^)  m/s²
Explanation:
This problem is an exercise of movement in two dimensions, the best way to solve it is to decompose the terms and work each axis independently.
 Break down the speeds in two moments
initial
   v₀ₓ = v₀ cos θ
   v₀ₓ = 5.25 cos 35.5
 v₀ₓ = 4.27 m / s
    = v₀ sin θ
 = v₀ sin θ
   = 5.25 sin35.5
= 5.25 sin35.5
  = 3.05 m / s
 = 3.05 m / s
Final
 vₓ = 6.03 cos (-56.7)
 vₓ = 3.31 m / s
  = v₀ sin θ
 = v₀ sin θ
  = 6.03 sin (-56.7)
 = 6.03 sin (-56.7)
  = -5.04 m / s
 = -5.04 m / s
Having the speeds and the time, we can use the definition of average acceleration that is the change of speed in the time order
     a = ( - v₀) /t
 - v₀) /t
     aₓ = (3.31 -4.27)/3 
     aₓ = -0.32 m/s²
      = (-5.04-3.05)/3
 = (-5.04-3.05)/3
     =  -2.697 m/s²
 =  -2.697 m/s²
 
        
             
        
        
        
Answer:
 
 
Explanation:
Initial speed, v = 10 x 10^3 m/s
Mass of the earth, M = 6 x 10^24 kg
Radius of the earth, R = 6.4 x 10^6 m
Maximum from the surface of earth, h = ?
Let  m = Mass of the projectile
Solution:
Potential energy at maximum height =  ( Potential + Kinetic energy ) at the surface

Answer: 8000N
Explanation: since it is frictionless that means it has 100% efficiency therefore the mechanical advantage is 1 meaning the load equals to the effort
