In order to compute the final velocity of the trains, we may apply the principle of conservation of momentum which is:
initial momentum = final momentum
m₁v₁ = m₂v₂
The final mass of the trains will be:
10,000 + 10,000 = 20,000 kg
Substituting the values into the equation:
10,000 * 3 = 20,000 * v
v = 1.5 m/s
The final velocity of the trains will be 1.5 m/s
Answer:
0.99 seconds
Explanation:
The problem depicts a simple harmonic motion.
Now, from Hooke's law,
The spring constant is given as;
k =F/x
where:
x is the displacement of the spring's end from its equilibrium position
F is the restoring force exerted by the spring on that end
From the question, F = 20N while x = 10cm = 0.1m. Thus,
K = 20/0.1 = 200 N/m
Now, time to take for the mass to return to its starting point is a period
The period oscillation of the mass is given as;
T = 2π√m/k
Where m = mass = 5kg
T = 2π√(5/200)
T = 0.99 s
