An object moving north with an initial velocity of 14 m/s accelerates 5 m/s2 for 20 seconds. What is the final velocity of the object?

Use the constant-acceleration equation: final velocity = initial velocity + (acceleration × time). Substituting the values gives 14 m/s + (5 m/s² × 20 s) = 114 m/s, so the final velocity is 114 m/s (choice C).
