Answer:
Newton's second law
Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
Explanation:
The specific heat of the metal, assuming no heat is exchanged with the surroundings is 2140 J/(kg•K).
<h3>
Specific heat capacity of the metal</h3>
The specific heat capacity of the metal is determined from the principle of conservation of energy.
energy lost by the metal = energy gained by aluminum + energy gained by water
Q = mcΔθ
where;
- m is mass (kg)
- c is specific heat capacity
- Δθ is change in temperature
0.425c(100 - 40) = 0.1(900)(40 - 15) + 0.5(4186)(40 - 15)
25.5c = 2250 + 52,325
c = 54,575/25.5
c = 2140 J/(kg•K)

Answer:
When the y-coordinate is 12m, the x-coordinate of the particle is 24 m
Explanation:
Given;
y - component of acceleration = 1 m/s²
X - component of acceleration = 2 m/s²
distance traveled in y - direction, Dy = 12 m
To determine the distance traveled in X- direction, we obtain the duration of the displacement in y- direction.
Applying equation of motion;
Dy = ¹/₂ x at²
For distance traveled in x -direction;
Dx = ¹/₂ x at²
Dx = ¹/₂ x 2 x (4.9)² = 24.01 m ≅ 24m
Therefore, when the y-coordinate is 12m, the x-coordinate of the particle is 24 m
