Question

Use the equation for motion to answer the question.

x=x0+v0t+12at2


An object has a starting position of 2 m, a starting velocity of 15 m/s, and is moving at a constant speed. Which option shows the final position of the object after 1 s?

(1 point)

17 m

60 m

32 m

30 m

Answer 1

Acceleration is zero (constant speed), so a = 0.
x = x0 + v0 t + 1/2 a t^2 = 2 + 15(1) + 0 = 17 m.

Answer: 17 m.
