Answer:
a) 12.8 N
b) 3.2 m/s²
Explanation:
I'm guessing the period is 0.5π s.
Period of a spring in simple harmonic motion is:
T = 2π √(m/k)
Given T = 0.5π and m = 2 kg:
0.5π = 2π √(2/k)
0.25 = √(2/k)
0.0625 = 2/k
k = 32
The spring constant is 32 N/m, and the maximum displacement is 0.4 m. The maximum force can be found with Hooke's law:
F = kx
F = (32 N/m) (0.4 m)
F = 12.8 N
The acceleration can be found with Newton's second law:
∑F = ma
kx = ma
(32 N/m) (0.2 m) = (2 kg) a
a = 3.2 m/s²

-formation of volcanoes
Convergent boundary plate tectonic involves collisions between oceanic and continental plates. The thinner and less denser oceanic plate overriden by the thicker and more denser continental plate. The oceanic plate is forced down the mantle, this event is known as subduction. The magma present in the mantle causes melting of subduction plates. The magma enters inside these plates through pores. This magma plate becomes bouyant and moves upwards. The molten magma causes volcanic eruptions along with earthquakes. If the magma solidifies in the subduction zone it creates mid ocean ridges. The mountains are formed near the continents when the magma after volcanic eruption gets cooled and solidified.
All the events are associated with convergent boundaries. Creation of mid-ocean ridges, Creation of new mountains, and formation of earthquakes.
What are convergent boundaries?
A convergent boundary occurs when two or more lithospheric plates clash on Earth. Subduction is the process through which one plate moves beneath the other.
The events are associated with convergent boundaries are;
1 . Creation of mid-ocean ridges
2. Creation of new mountains
3. Formation of earthquakes
4. Formation of volcanoes
Collisions between oceanic and continental plates are involved in convergent boundary plate tectonics. The oceanic plate, which is thinner and less dense, is pushed aside by the continental plate,
Which is thicker and denser. Subduction occurs when an oceanic plate is driven down into the mantle. The melting of subduction plates is caused by magma in the mantle.
The magma seeps into the pores of these plates. This magma plate rises as it gets buoyant. Volcanic eruptions and earthquakes are both caused by molten magma.
Mid-ocean ridges form as magma solidifies in the subduction zone. Mountains are generated near continents as lava cools and solidifies following a volcanic eruption.

Explanation:
Decrease the friction between the wheels and the track. Friction opposes motion. If the amount of friction is decreased, the speed of the cars should increase.
