Answer :
Final answer:
To find the final velocity, use the equation final velocity = initial velocity + (acceleration * time). By substituting the given values, the final velocity is approximately +37.94 m/s, which is closest to +39.4 m/s.
Explanation:
To find the final velocity, we use the equation:
final velocity = initial velocity + (acceleration * time)
Given:
Initial velocity (v0) = +20 m/s
Acceleration (a) = +2.3 m/s²
Time (t) = 7.8 seconds
Substituting the given values into the equation:
final velocity = +20 m/s + (+2.3 m/s² * 7.8 s)
final velocity = +20 m/s + 17.94 m/s
final velocity = +37.94 m/s
Therefore, the final velocity is approximately +37.94 m/s. The closest option to this value is a) +39.4 m/s.
