Answer:

3miles per hour^2

Step-by-step explanation:

given data

initial speed u= 15mph

final speed v=45mph

time taken t= 10 seconds

Step two:

Required

acceleration a=?

applying the first equation of motion

v=u+at

substitute we have

45=15+a*10

45=15+10a

make a subject of the formula

45-15=10a

30=10a

divide both sides  by 10

a=30/10

a=3miles per hour^2

The temperature dropped 5 degrees every hour during 8 hours. How much the temperature drop in all?
Murrr4er [49]

Answer:

<h3>40 degrees</h3>

Step-by-step explanation:

If the temperature dropped 5 degrees every hour, this can be expressed as;

5 degree = 1 hour

To get the total number of degree dropped fro 8hours, we will say;

x degree = 8hours where x is the temperature drop in all

Solving both equality

5 degree = 1 hour

x degree = 8 hours

cross multiply

x * 1 = 5 * 8

x = 40 degrees

<em>Hence the total temperature drop in all is 40°</em>
