Matter is made of single particles called atoms and is any substance that has either mass or volume. Matter can exist in three states, either as a solid, a liquid or a gas. When two or more atoms combine, they form molecules and Atoms are made up of three sub-atomic protons called protons, neutrons and electrons. The protons and neutrons are densely packed together in the nucleus

A frictionless block of mass 2.10 kg is attached to an ideal spring with force constant 250 N/m . At t=0 the spring is neither s

Mamont248 [21]

Answer:

Explanation:

Given

mass of block $m=2.12 kg$

spring constant $k=250 n/m$

speed of block at t=0 is $v=13 m/s$

natural Frequency of oscillation $\omega _n=\sqrt{\frac{k}{m}}$

$\omega _n=\sqrt{\frac{k}{m}}$

$\omega _n=\sqrt{\frac{250}{2.12}}$

$\omega _n=\sqrt{117.92}$

$\omega _n=10.85 rad/s$

Suppose $x=A\cos (\omega _nt+\phi )$

where $\phi =Phase\ difference$

at t=0 spring is neither compressed

Amplitude is given by

$A=\sqrt{x^2+(\frac{v}{\omega })^2}$

at t=0 x=0 i.e. at mean Position

$A=\sqrt{0+(1.198)^2}$

$A=1.198 m$

at $t=0$

$x=A\cos (\omega _nt+\phi )$

$x=1.198\cos (0+\phi )$

$0=\cos (\phi )$

therefore $\phi =\frac{\pi }{2}$

in a design of a passenger bus it is proposed to derive the motive power from the energy stored in fly wheel. the fly wheel has

Dahasolnce [82]

Answer:

$5*10^{5} Joule$

Explanation:

Total rotational kinetic energy = $\frac{1}{2}*Inertia(angular speed)^{2}$

(Here fly wheel may have translational kinetic energy but we ignore here)

Angular speed = 3000 revolutions per minute

Angular speed = $\frac{3000}{60}=50$ revolutions per second

Thus , Kinetic energy = $\frac{1}{2}*400\frac{3000}{60} ^{2}$

= $5*10^{5} Joule$
