A truck is stopped at a stop sign. After realizing the driver should go straight, he accelerates the truck at a constant rate of
1 answer:
Answer:
v = 33.8 m/s
Step-by-step explanation:
Given that,
The initial velocity of the truck, u = 0
Acceleration of the truck, a = 3.6 m/s²
Time, t = 9.4 s
We need to find the car's final velocity. Let v is the final velocity.
Using equation of kinematics as follows :
v = u +at
Since, u = 0
Hence, the final velocity of the car is 33.8 m/s.

I'm not sure what you mean by this part of your question. It is possible to represent any real number as a complex number, but not a purely imaginary one. All real numbers are complex, but not all complex numbers are real. For example, 2 is real and complex because .
There are some operations that you can carry out on purely imaginary numbers to get a purely real number. A famous example is raising to the
-th power. Since
, we have
