SOLUTION: an automobile moving at 15m/s starts at accelerate at a rate of 3m/s. find its velocity 5 seconds later

Question 1072312: an automobile moving at 15m/s starts at accelerate at a rate of 3m/s. find its velocity 5 seconds later

Answer by rothauserc(4718) (Show Source): You can put this solution on YOUR website!
initial velocity(V(i)) is 15 m/s
:
acceleration(a) = 3 m/s
:
time(t) = 5 seconds
:
a = (V(f) - V(i)) / t
:
3 = (V(f) - 15) / 5
:
V(f) - 15 = 15
:
V(f) = 30
:
