How do you find a rate of deceleration

Physics

To find the deceleration of the object. We need to know what is the speed the object is slowing down to, in this case it would be final velocity of 0.

Vi = 75
Vf = vi + at
0 = 300a + 75
-75 m/s = 300a
-75/300 = a
-0.25 m/s^2 = a.

The train slows down at this rate a = -0.25 m/s^2.


5 min = 5 • 60 = 300 seconds

storchak [24]

Answer:

The atomic number is the number over the symbol of the element in the periodic table and the atomic mass the number under it. An isotope is an atom with more or less neutrons than its regular form. a neon atom with mass number of 22 will have 12 neutrons in the nucleus and 10 protons, draw it with its 10 electrons. Two electrons go in the first level of energy and eight in the second. Draw a nucleus with 10 protons and 12 neutrons and an arc with 2 electrons around it and another arc with 8 electrons over the first arc.

How can u tell matched forces act on objects?
mamaluj [8]

Answer:If an object's speed changes, or if it changes the direction it's moving in,

then there must be forces acting on it. There is no other way for any of

these things to happen.

Once in a while, there may be a group of forces (two or more) acting on

an object, and the group of forces may turn out to be "balanced".  When

that happens, the object's speed will remain constant, and ... if the speed

is not zero ... it will continue moving in a straight line.  In that case, it's not

possible to tell by looking at it whether there are any forces acting on it
