Answer:
a = -8.912 m/s²
Explanation:
Given,
The initial velocity of the car, u = 28 m/s
The final velocity of the car, v = 0
The distance traveled by car, d = 88 m
The velocity displacement relation is given by the formula
v = d/t
∴ t = d/v
Substituting in the above values in the given equation
t = 88/28
= 3.142 s
The acceleration is given by the formula
a = (v-u)/t
= (0 - 28)/3.142
= -8.912 m/s²
The negative sign is that the car is decelerating.
Hence, acceleration a = -8.912 m/s²
I think it will go down like decrease minus or whatever you call it
Measuring the heat of chemical reactions or physical changes.
Answer:
Yes, it would be enough.
Explanation:
The volume of the tank (cylinder tank) is given by the following equation:

Where:
D is the diameter of the tank
h is the height of the tank
Now, the engineer makes a tank 1.26 times as big in heigh and 1.41 times as large with respect to diameter, then the new volume of this tank will be:


in terms of the initial volume:

Which means that the volume of the water could be doubled.
I hope it helps you!
