A mass m is attached to a spring which is held stretched a distance x by a force f (fig. 7-28), and then released. the spring co

guapka [62]

Spring is stretched by force f to distance "x"

now here by force balance we can say

$f = kx$

$k = \frac{f}{x}$

now here we will we say that energy stored in the spring will convert into kinetic energy

$\frac{1}{2} kx^2 = \frac{1}{2}mv^2$

$\frac{f}{x} (x^2} = mv^2$

now solving above equation we will have

$v =\sqrt{ \frac{fx}{m}}$

PART 2)

now for half of the extension again we can use energy conservation

$\frac{1}{2}kx^2 - \frac{1}{2}k(x/2)^2 = \frac{1}{2} mv^2$

$\frac{3}{4}kx^2 = mv^2$

$\frac{3}{4}fx = mv^2$

now the speed is given as

$v = \sqrt{\frac{3fx}{4m}}$

An elastic collision is one in which:

julia-pushkina [17]

Answer:

.conserves kinetic energy and momentum

.does not coalesce

.causes much lesser deformation as compared to inelastic

.the two bodies involved; after collision move with separate final velocities.

Explanation:

eg. throwing a ball at a wall

collision between a punch and your nose,haha

I guess that will cause a lot deformation..

A charge Q is uniformly spread over one surface of a very large nonconducting square elastic sheet having sides of length d. At

Umnica [9.8K]

Answer:

Explanation:

Given

Charge Q is uniformly spread over large non-conducting Elastic sheet

Electric field due to non-conducting Elastic sheet

$E=\frac{\sigma }{2\epsilon }$

where $\sigma =$ surface charge density $=\frac{q}{d^2}$

$E=\frac{\frac{q}{d^2}}{2\epsilon }$

for side 2d Electric Field is given by

$E'=\frac{\frac{q}{2d^2}}{2\epsilon }$

$E'=\frac{1}{4}\times \frac{\frac{q}{d^2}}{2\epsilon }$

$E'=\frac{E}{4}$
