Answer:
v_0(initial velocity) v_f(final velocity) a(acceleration)
v_0=70 km/h v_f= 0 km/h( rest)
Kinematics equation is a=(v_f-v-0)/time
a=(0-70)/(7/3600) which means it decelerates at -36000 km/h
This number is humongous; I would advise you to re-check the problem and see if the the time it takes is 7 hours rather than 7 seconds. Notice that I put the time as 7/3600 because it is 7 seconds which should be converted to hours.

Actually Welcome to the Concept of the Volumes.
==> Volume is Basically defined as the amount of a substance any shape or an object can hold.
==> Volume just can be tendency of any object to hold maximum amount of Substance inside it.
Answer:
- 6 m/s
Step-by-step explanation:
The rate of change is a measure of the slope and can be calculated using the slope formula
m = 
with (x₁, y₁ ) = (2, 78) and (x₂, y₂ ) = (10, 30) ← 2 points on the line
m =
=
= - 6
Rate of change is - 6 m/s
X=3 Should be the answer If you ser 2x-3=5x-12
-2x -2x
-3=3x-12
+12 +12
9=3x
3=x
Answer:
x=2
Step-by-step explanation:
5x-7=5-x
5x=12-x
6x=12
x=2
