No official standard exists for extinguisher-cylinder colors. that said, a red cylinder is typically associated with which type

It’s important to note that ‘the cart or spring is situated on a frictionless horizontal track’, which means there are no frictional forces acting on them.

Explanation:

a) Per the scenario, when the cart is drawn to position A and then let go, its initial speed at A (at time t=0) is 0 m/s. The cart travels toward position E, reaches a point where it reverses direction, and then heads back to position A. During this second phase, as the cart travels from A to E, its speed increases until it becomes zero again at point E, at which point it changes direction again, thus

b) Let’s assume the distance between two successive points is x meters and the spring constant is k N/m

c) ( File has been attached)

d) Moving to the right

e) Moving to the left

Answer
graph 2

Explanation
Velocity refers to the speed at which displacement changes.
Velocity = (change in displacement)/(change in time)
In graph 2, the slope of the curve is positive, indicating a positive velocity.
Acceleration indicates how velocity varies.
The incline of the same curve (graph 2) is diminishing. This suggests that the velocity is falling, signifying negative acceleration.
