An automobile with an initial speed of 6.60 m/s accelerates uniformly at the rate of 3.9 m/s^2
Find the final speed of the car after 5.2s
Answer in units of m/s
To find the final speed of the car, we can use the equation:
final speed = initial speed + (acceleration * time)
Given:
Initial speed (u) = 6.60 m/s
Acceleration (a) = 3.9 m/s^2
Time (t) = 5.2 s
Substituting the given values into the equation:
final speed = 6.60 m/s + (3.9 m/s^2 * 5.2 s)
Calculating the expression:
final speed = 6.60 m/s + 20.28 m/s
final speed = 26.88 m/s
Therefore, the final speed of the car after 5.2 seconds is 26.88 m/s.
