Block with m = 300 grams oscillates at the end of a linear spring with k = 6.5 N/m. (assume this is a top-down view and the bloc
masha68 [24]

Explanation:

Given that,

Mass of the block, m = 300 g = 0.3 kg

Linear spring constant, k = 6.5 N/m

(a) Let T is the period of the block's motion. It is given by :

T=\dfrac{2\pi}{\omega}

where

\omega=\sqrt{\dfrac{k}{m}}= angular frequency

Also, \omega=\sqrt{\dfrac{k}{m}}

T=\dfrac{2\pi}{\sqrt{\dfrac{k}{m}}}

T=\dfrac{2\pi}{\sqrt{\dfrac{6.5}{0.3}}}

T = 1.34 seconds

(b) The maximum acceleration of the block is, a_{max}=2\ m/s^2

The maximum acceleration is given by :

a_{max}=\omega^2A

A is the amplitude of the motion,

A=\dfrac{a_{max}}{\omega^2}

A=\dfrac{a_{max}}{(\sqrt{\dfrac{k}{m}})^2}

A=\dfrac{ma_{max}}{k}

A=\dfrac{0.3\times 2}{6.5}

A = 0.09 meters

Hence, this is the required solution.

Describe the concept that defines weather an object
xz_007 [3.2K]

An object has identity(each object is a distinct individual). An object has state(it has various properties, which might change). An object has behavior(it can do things and can have things done to it). This is a somewhat ordinary description of what an object is like.

A child is holding a wagon from rolling straight back down in a driveway that inclined at 20 degree horizontal. if the wagon wei
Digiron [165]

Answer:

F = 51.3°

Explanation:

The component of weight parallel to the inclined plane must be responsible for the rolling back motion of the car. Hence, the force required to be applied by the child must also be equal to that component of weight:

F = Parallel\ Component\ of\ Weight\ of\ Wagon= WSin\theta\\

where,

W = Weight of Wagon = 150 N

θ = Angle of Inclinition = 20°

Therefore,

F = (150\ N)Sin\ 20^o

<u>F = 51.3°</u>

The black lines that wrap themselves around a basketball represent an example of what type of geometry?
Dmitry [639]
In Euclidean geometry parallel lines never intersect. But in non-Euclidean geometry parallel lines can either curve away from each other, or curve towards each other. Example : the black lines that wrap themselves around the basketball.
Answer: B ) non-Euclidean
