Answer:
-3.1 m/s²
Explanation:
Given data
- Initial speed (v₀): 20 m/s
- Final speed (vf): 0 m/s (the automobile stops)
- Elapsed time (t): 6.5 seconds
- Acceleration (a): to be determined
We can determine the acceleration of the automobile using the following kinematic expression.
a = Δv / t
a = vf - v₀ / t
a = (0 m/s - 20 m/s) / 6.5 s
a = -3.1 m/s²
Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two. Where: ¯v = average velocity.
Hope this helps :)
And could i please have brainliest
Answer:
3
Explanation:
left side has 2 N so right side must have a 2 which means 6 H on right side so to get 6 on left you have a coef. of 3 to make 6 H
