Answer:
the final angular velocity of the particle is approximately 38.18 Rad/s
Explanation:
To start with, let's make sure that units of angle measure are the same, converting everything into radians:
And now we can use the kinematic formulas for rotational motion:
Therefore we can find the initial angular velocity of the particle:
and now we can estimate the final angular velocity using the kinematic equation for angular velocity;
<h3>Derivation of Conservation of Momentum</h3>
Applying Newton's third law, these two impulsive forces are equal and opposite i.e. If the time of contact is t, the impulse of the force F21 is equal to the change in momentum of the first object. The impulse of force F12 is equal to the change in momentum of the second object.
<h2>MARK ME BRAINLIST</h2>
Answer:
959183.7 kg
Explanation:
from the question we have :
young modulus = 5 x 10^{9} N/m^{2}
strain = 2% = 2÷100 = 0.02
diameter = 0.03 m
radius = 0.015 m
acceleration due to gravity (g) = 9.8 m/s^{2}
we can get the mass from the formula below
young modulus = stress ÷ strain
where
stress = \frac[force}{area} = \frac {mass x g}{area}
area = 2πr = 2π x 0.015 = 0.094
therefore
young modulus = \frac{\frac {mass x g}{area}}{strain}
5 x 10^{9} = \frac{\frac {mass x 9.8}{0.094}}{0.02}
mass = \frac{5 x 10^{9} x 0.02 x 0.094}{9.8}
mass = 959183.7 kg
