Question

ariana is accelerating her car at 4.6 m/s2 it took her 10 seconds to reach this acceleration her starting velocity was om/s what was her final velocity

Answer 1

Acceleration of the car = 4.6 m/s^2
Initial time taken (T1)  = 0 second
Final time taken (T2) = 10 seconds
Initial velocity of the car (V1) = 0 m/s
Let us assume the final velocity of the car (V2) = x m/s
Then
Acceleration of the car = (V2 - V1)/(T2 - T1)
4.6 = (x - 0)/(10 - 0)
4.6 = x/10
x = 4.6 * 10
  = 46 m/s
So the final velocity of the car Ariana is driving is 46 m/s.I hope the procedure is clear enough for you to understand. In future you can always use this procedure for solving similar problems without requiring any help from outside.
