a body initially at rest, starts moving with a constant acceleration of 2ms-2 .calculate the velocity acquired and the distance
Marta_Voda [28]

a) 10 m/s

b) 25 m

Explanation:

a)

The body is moving with a constant acceleration, therefore we can solve the problem by using the following suvat equation:

v=u+at

where

u is the initial velocity

v is the final velocity

a is the acceleration

t is the time

For the body in this problem:

u = 0 (the body starts from rest)

a=2 m/s^2 is the acceleration

t = 5 s is the time

So, the final velocity is

v=0+(2)(5)=10 m/s

b)

In this second part, we want to calculate the distance travelled by the body.

We can do it by using another suvat equation:

v^2-u^2=2as

where

u is the initial velocity

v is the final velocity

a is the acceleration

s is the distance travelled

Here we have

u = 0 (the body starts from rest)

a=2 m/s^2 is the acceleration

v = 10 m/s is the final velocity

Solving for s,

s=\frac{10^2-0^2}{2(2)}=25 m

Why e=mc2?why not e=mc3?
Softa [21]
For starters, this question isn’t really about relativity. It’s about energy, and E=mc^2 only makes sense if energy has the units of (mass)*(velocity)^2. So we might as well ask: why is kinetic energy defined as KE = ½*mv^2?

An animal keeper is studying X-rays of two animals, as shown. X-rays show the internal structures of an animal.
saveliy_v [14]
<span>Animal Y is an invertebrate, and animal Z is a vertebrate. 

An x-ray can produce images of structures found inside the body. Based on the image, you can see that Animal Z has a backbone, which is a series of small bones called vertebrae that extend from the head. Animal Y does not have that structure. 

Vertebrates are organisms that have a backbone and invertebrates are organisms that lack one. </span>
