Question

If the acceleration in question 8 is constant, what's the average velocity of the object described?

Answer 1

Answer: average velocity = initial velocity + 1/2 acceleration* time

Explanation:Q8 unavailable, but at constant acceleration a

if initial velocity is v1, final velocity v2 and average velocity (v1+v2)/2 and the time interval t,

v2 = v1 + at and average velocity = v1 + 1/2at

Answer 2

Final Answer:

If the acceleration in question 8 is constant, the average velocity of the object can be found by adding its initial and final velocities and dividing the result by 2.

Step-by-step explanation:

When acceleration is constant, the relationship between acceleration, initial velocity, final velocity, and displacement can be described by the kinematic equation:

a is the acceleration, and

t is the time. To find average velocity (

is applied. This is derived from the fact that the average velocity over a constant acceleration interval is the arithmetic mean of the initial and final velocities. So, the average velocity is the sum of the initial and final velocities divided by 2.

Option C is the answer.
