A bike travels at a constant speed of 4.0 m/s for 5.0 s. How far does it go?

GIVEN:
V = 4.0 m/s
t = 5.0 s

Would you use this equation?
D= Vit + 1/2 at^2

  1. Yes, the equation
    D= Vit + 1/2 at^2
    is appropriate with or without acceleration.

    Constant speed means that the acceleration (a) is zero, so the second term disappears to degenerate into the more familiar equation:
    Distance = Speed * Time.
