Answer:
Step-by-step explanation:
Given
--- acceleration
--- final velocity
--- initial velocity (it is 0, because the car starts from rest)
Required
Determine the time taken
This will be solved using Newton's first equation of motion:
Substitute values for v, u and a
Make t the subject
<em>Hence, the time taken is approximately 5.2 seconds</em>
Answer: OPTION B.
Step-by-step explanation:
1. By definition, the line intercepts the x-axis when y=0. Therefore, you must susbtitute y=0 into the equation of the line given in the problem and solve for x, as you can see below:
2. Knowing that the x-intercept of the line from the equation and is -2 and the x-intercept from the description is (0,0), you can conclude that the correct option is B.
