Physical Science Final Exam Practice

Nora is riding her bicycle and starts pedaling faster. If her initial velocity (v_i) is 5 m/s, and she accelerates at a rate of 2 m/s² for 3 seconds, what is her final velocity (v_f)?

• v_f = v_i + at

• v_f = v_i - at

• v_f = v_i * at

• v_f = v_i / at

Jackson is driving his car and wants to calculate the distance (d) he travels. He knows his initial velocity (v_i), final velocity (v_f), and the time (t) he has been driving. What is the formula for distance (d) in terms of these variables?

• d = 1/2(v_f + v_i)t

• d = v_i t + 1/2 v_f t

• d = v_f t - v_i t

• d = (v_f - v_i)/t

David is riding his bicycle with an initial velocity (v_i) and accelerates at a constant rate (a) for a certain time (t). What is the formula for the distance (d) he travels?

Aiden is driving a car and wants to calculate the final velocity squared (v_f^2) of his car in terms of the initial velocity squared (v_i^2), acceleration (a), and distance (d) traveled. What formula should he use?
