To answer, first, convert the given velocity in km/h to m/s as shown below,
(144 km / hr) x (1000 m / 1 km) x (1 hr / 3600 s) = 40 m/s
The acceleration (a) is solved by through the equation,
a = (Vf - Vi) / Δt
where Vf and Vi are final and initial velocities, respectively and Δt is change in time. Substituting the known values,
a = (0 - 40 m/s) / 12 s = -3.3 m/s²
Thus, the answer to this item is letter B.

Answer:
e=14
Step-by-step explanation:
15/21 =10/e
by cross multiplying,
e×15=21×10
15e=210
e=210/15
e=14
Answer:
Angle K is congruent to itself, due to the reflexive property
Step-by-step explanation:
Given: ΔLKM is similar to ΔNOM
To find: statement that is not used to prove that ΔLKM is similar to ΔNOM
Solution:
Two figures are said to be congruent if they have same shape and same size.
Two figures are said to be similar if they have same shape but different size.
If two figures are similar then their corresponding angles are equal.
As ΔLKM
ΔNOM,

So, statement that can be used to prove that ΔLKM is similar to ΔNOM is ''Angle K is congruent to itself, due to the reflexive property''
