An object has a starting position of x = 2 m, a starting velocity of 4.5 m/s, and no acceleration. Which option shows the final position of the object after 2 s?\

Question

11m
9m
18m
5.5m

Answer 1

The final position of the object can be calculated using the equation:

final position = initial position + (initial velocity * time) + (0.5 * acceleration * time^2)

Since there is no acceleration, the equation simplifies to:

final position = initial position + (initial velocity * time)
final position = 2 + (4.5 * 2)
final position = 2 + 9
final position = 11m

Therefore, the correct answer is 11m.
