Answer:
The value is 
Explanation:
From the question we are told that
The diameter of each wheel is 
The mass of the motorcycle is 
The rotational kinetic inertia is 
The mass of the rider is 
The velocity is 
Generally the radius of the wheel is mathematically represented as
=> 
=> 
Generally from the law of energy conservation
Potential energy attained by system(motorcycle and rider ) = Kinetic energy of the system + rotational kinetic energy of both wheels of the motorcycle
=> 
=> 
Here 
is the angular velocity which is mathematically represented as
So
Here 
![395 * 9.8 * h = 0.5 * 395 * (23.61)^2 + 2.1 *[\frac{ 23.61}{ 0.26} ] ^2](https://tex.z-dn.net/?f=395%20%2A%20%209.8%20%2A%20%20h%20%20%3D%20%20%200.5%20%20%20%20%2A%20%20%20395%20%2A%20%20%2823.61%29%5E2%20%2B%20%202.1%20%20%2A%5B%5Cfrac%7B%2023.61%7D%7B%200.26%7D%20%5D%20%5E2)
=>
1/s' = 1/f - 1/s
= 1/12 - 1/8
= 2/24 - 3/24
= 2-3/24
= - 1/24
s'= -24
M= |s'/s|
M = |24/8|
M = 3
Answer:
Learned helplessness can have a profound impact on mental health and well-being. People who experience learned helplessness are also likely to experience symptoms of depression, elevated stress levels, and less motivation to take care of their physical health. Not everyone responds to experiences the same way.
Explanation:
Brainlist will be very accepted ;D *wink*
The object's final velocity, using the impulse-momentum theorem, is 20 i +7 j.
<h3>What is kinetic energy?</h3>
- A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
- Kinetic energy comes in five forms: radiant, thermal, acoustic, electrical, and mechanical.
- The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.
- Explain that a moving object's mass and speed are two factors that impact the amount of kinetic energy it will possess.
Calculate the object's final velocity using the impulse-momentum theorem.
mass of object m = 3 kg
Initial velocity u = 7 j
net force F = 12 i
Time t = 5 s
(1). Impulse J=F t
= 12 i x 5
= 60 Ns i
We know J = m( v-u)
v- u = J / m
= 60 i / 3
= 20 i
v = 20 i + u
= 20 i +7 j
The object's final velocity, using the impulse-momentum theorem, is 20 i +7 j.
