The kinetic energy of this block-spring when the block has a speed (v) is given by K.E = 1/2 × (M + m/3)v².
<h3>What is kinetic energy?</h3>Kinetic energy can be defined as a form of energy that is possessed by a person due to its motion or change in speed (acceleration).
<h3>How to calculate kinetic energy?</h3>Mathematically, kinetic energy can be calculated by using this formula:
K.E = 1/2 × mv²
Where:
- K.E represents the kinetic energy.
- m represents the mass.
- v represents the speed or velocity.
Since the mass of a segment of this spring is dm = (m/l) dx, the kinetic energy for each of its segment would be given by:
dK = 1/2 × (dm)Vx²
This ultimately implies that, the kinetic energy of this block-spring when the block has a speed (v) is given by:
K.E = 1/2 × Mv² + 1/2 × ¹∫₀((x²v²/l²)m/ldx
K.E = 1/2 × (M + m/3)v².

Answer:
Explanation:
Given that,
Mass of ball 1,
Initial speed of ball 1,
Mass of ball 2,
Initial speed of ball 2, (at rest)
After the collision,
Final speed of ball 2,
Let is the final speed of ball 1.
Initial momentum of the system is :
Final momentum of the system is :
According the law of conservation of linear momentum :
initial momentum = final momentum
So, the final velocity of ball 1 is (-2.616)m/s.
Answer:
T = 365.58 K
Explanation:
Given that,
The concentration of solution, C = 0.750M
Osmotic pressure, P = 22.5 atm
We need to find the temperature of the solution.
The formula for the osmotic pressure is given by :
Where
R is gas constant,
So, the temperature of the solution is 365.58 K.
