answer

45J

explanation

kinetic energy can be found through the equation $K = \frac{mv^2}{2}$

plug in 10 for m (mass) and 3 for v (velocity)

$K = \frac{mv^2}{2}\\K = \frac{10*3^2}{2}\\K = \frac{10*9}{2}\\K = \frac{90}{2}\\K = 45 J$

You hold a spherical salad bowl 50 cm in front of your face with the bottom of the bowl facing you. The salad bowl is made of po

nataly862011 [7]

Answer:

a) q = 39.29 cm , b) h ’= - 3.929 cm the image is inverted and REAL

Explanation:

For this exercise we will use the equation of the constructor

1 / f = 1 / p + 1 / q

where f is the focal length of the salad bowl, p and q are the distance to the object and the image

The metal salad bowl behaves like a mirror, so its focal length is

f = R / 2

f = 44/2

f = 22 cm

a) Suppose that the distance to the object is p = 50 cm, let's find the distance to the image

1 / q = 1 / f - 1 / p

1 / q = 1/22 - 1/50

1 / q = 0.0254

q = 39.29 cm

b) to calculate the size of the image we use the equation of magnification

m = h’/ h = - q / p

h ’= - q / p h

h ’= - 39.29 / 50 5

h ’= - 3.929 cm

the negative sign means that the image is inverted

as the rays of light pass through the image this is REAL

A missle is fired horizontally with an initial velocity of 45 m/s from the top of a building 75 m high.

NARA [144]

The horizontal range of the missile is b) 176 m

Explanation:

The motion of the missile is a projectile motion, so it consists of two independent motions:

- A uniform motion with constant velocity along the horizontal direction

- A uniformly accelerated motion with constant acceleration (equal to the acceleration of gravity) in the vertical-downward direction

To find the time of flight of the missile, we study the vertical motion. We can use the following suvat equation:

$s=u_y t+\frac{1}{2}at^2$

where:

s = 75 m is the vertical displacement of the missile (the height of the building)

$u_y=0$ is the initial vertical velocity (the missile is thrown horizontally)

t is the time of flight

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

Solving for t, we find the time of flight:

$t=\sqrt{\frac{2s}{g}}=\sqrt{\frac{2(75)}{9.8}}=3.91 s$

This means that the missile takes 3.91 s to reach the ground.

Now we study the horizontal motion: the missile moves with a constant horizontal velocity of

$v_x = 45 m/s$

Therefore, the distance covered in a time t is

$d=v_x t$

and by substituting t = 3.91 s, we find the horizontal range of the missile:

$d=(45)(3.91)=176 m$

What's so great about solar energy systems?

Marta_Voda [28]

Solar energy is a good alternative to replace fossil fuel as the major energy source because solar power is renewable at absolutely no cost to supply energy infinitely.
