Answer:
Total Resistance in circuit is Fourteen Ohms <u>(14 Ω).</u>
<u></u>
Explanation:
How do we know, if the resistors are connected in series, the total resistance is the <u>sum of all the resistors.</u>
(Important: The total resistance can only be added just when the resistors are <u>connected in series</u>)
Then, total resistance (<em>TR </em>) is the sum of all resistors (<em>T1 + T2</em>, in this case)
TR = T1 + T2
According to problem data, we have:
TR = 8 Ω + 6 Ω
TR = 14 Ω

The value of the acceleration is 0.76 m/s² and the total time taken by the vehicle is 39 seconds.
<h3>Acceleration of the vehicle</h3>
The acceleration of the vehicle before coming to rest is calculated as follows;
v² = u² + 2as
where;
- v is the final velocity
- u is the initial velocity
- a is the acceleration
- s is the distance traveled before stopping
the car came to rest with constant velocity attained after 12 seconds.
the initial velocity of the car before 12 seconds is zero.
v² = 0 + 2as
a = v²/2s
a = (10²)/(2 x 66)
a = 0.76 m/s²
<h3>Time of motion of the vehicle</h3>
d = ut + ¹/₂at²
where;
- d is the total distance traveled
- t is the time of motion
- a is acceleration
- u is initial velocity of the vehicle
580 = 0 + ¹/₂(0.76)t²
580 = 0.38t²
t² = 580/0.38
t² = 1,526.3
t = √1,526.3
t = 39 seconds
Thus, the value of the acceleration is 0.76 m/s² and the total time taken by the vehicle is 39 seconds.
