A girl is bouncing on a trampoline where is her gravitational potential energy a maximum and where is her kinetic energy maximum

Stella [2.4K]

Answer:

When you jump down, your kinetic is converted to potential energy of the stretched trampoline. The trampoline's potential energy is converted into kinetic energy, which is transferred to you, making you bounce up. At the top of your jump, all your kinetic energy has been converted into potential energy. Right before you hit the trampoline, all of your potential energy has been converted back into kinetic energy. As you jump up and down your kinetic energy increases and decrease.

Starting from rest, a 75.0-kg snowboarder slides straight down a 115-m slope in 6.6 s. If the slope is a 35°

Likurg_2 [28]

The acceleration of the snowboarder is $5.6 m/s^2$ down along the incline

Explanation:

To find the acceleration of the snowboard, we have to analyze the forces acting along the direction parallel to the incline.

There is only one force acting in this direction, and it is the component of the weight parallel to the incline, given by

$mg sin \theta$

where

m = 75.0 kg is the mass of the man

$g=9.8 m/s^2$ is the acceleration of gravity

$\theta=35^{\circ}$ is the angle of the incline

Substituting, we find that the net force along the incline is:

$F=(75.0)(9.8)(sin 35^{\circ})=421.6 N$

According to Newton's second law, the net force on the snowboard is equal to the product between his mass and his acceleration:

$F=ma$

where a is the acceleration. Therefore, solving for a, we find

$a=\frac{F}{m}=\frac{421.6}{75}=5.6 m/s^2$

And the direction of this acceleration is down along the incline.

A laser with wavelength d/8 is shining light on a double slit with slit separation 0.500 mm. This results in an interference pat

ipn [44]

Answer:

0.000109375 m

Explanation:

d = Distance between grating = 0.5 mm

m = Order

$\lambda_1=\dfrac{d}{8}$

Minima relation

$m-\dfrac{1}{2}$

For fourth order minima

$dsin\theta=(4-\dfrac{1}{2})\lambda_1$

For second maxima

$dsin\theta=2\lambda_2$

From the two equations we get

$(4-\dfrac{1}{2})\lambda_1=2\lambda_2\\\Rightarrow \lambda_2=\dfrac{(4-\dfrac{1}{2})\lambda_1}{2}\\\Rightarrow \lambda_2=\dfrac{(4-\dfrac{1}{2})\dfrac{0.5\times 10^{-3}}{8}}{2}\\\Rightarrow \lambda_2=0.000109375\ m$

The wavelength is 0.000109375 m
