At a playground, a child slides down a slide that makes a 42° angle with the horizontal direction. The coefficient of kinetic fr
kumpel [21]

Answer:

a = 5.1\ m/s^2

Explanation:

Given,

The angle of the slide=42^\circ

The mass of the child is= m

coefficient of friction = 0.20

when she slides down now apply Newton's law

ma =mg \sin\theta - f

ma = mg\sin \theta -\mu mg \cos \theta

therefore the acceleration

a=g \sin\theta -\mu gcos\theta

a=g[\sin \theta -\mu \cos \theta]

a=9.8\times [\sin 42^\circ -0.2\times \cos 42^\circ]

a = 5.1\ m/s^2

hence, the magnitude of acceleration during her sliding is equal to  a = 5.1\ m/s^2

Anit [1.1K]

Answer:

Option A

Explanation:

The graph for this problem must depict the following ""Increased allocation of resources to reproduction relative to growth diminished future fecundity."

Hence, the survivor ship must be on the Y axis and the resources on the X axis.

Here the resources include the number of seeds produced.

hence, the higher is the number of seeds (resource), the lower is the survivorship (future fecundity)

Hence, option A is correct
