I'm pretty sure it's frying an egg because you can't un-fry the egg
Answer:
4776.98 N is the minimum force to start the rise.
Explanation:
We can use the first Newton's law to find the minimum force to move the block.
So we will have:
Where:
- F is the force
- W(x) is the weight of the block in the x direction, W = mg*sin(15)
- F(f) is the static friction force (F(f) = μN), μ is the static friction coefficient 0.4.
Therefore 4776.98 N is the minimum force to move the block.
I hope it helps you!
Answer:
<em>The kinetic energy is 600 J</em>
Explanation:
<u>Mechanical Energy</u>
The principle of the conservation of mechanical energy states that the total mechanical energy in a system remains constant as long as the only forces acting are conservative forces.
The mechanical energy is defined as the sum of the potential plus kinetic energies:
E = U + K
Where E is the total mechanical energy, U is the gravitational potential energy and K is the kinetic energy.
Solving for K:
K = E - U
The system described has a total mechanical energy of E=950 J and gravitational potential energy of U=350 J, thus:
K = 950 J - 350 J
K = 600 J
The kinetic energy is 600 J

The linear velocity of the wheel is 16 m/s.
<h3 /><h3>What is linear velocity?</h3>
Linear velocity is the rate of change of displacement with regard to time when the object is moving in a straight line
To calculate the linear velocity of the wheel, we use the formula below.
Formula:
- v = ωr............. Equation 1
Where:
- v = Linear velocity
- ω = Angular velocity
- r = Radius of the wheel.
From the question,
Given:
Substitute these values into equation 1
Hence, The linear velocity of the wheel is 16 m/s.
