Below are sample questions representative of the exercises included on this worksheet and related 12.61 Momentum as a Vector Quantity skill assessments:

Problem 1Difficulty: Mastery

A momentum vector changes from 30 kg·m/s north to 30 kg·m/s east. What is the magnitude and direction of the change in momentum?

A0 kg·m/s, because the magnitude stayed 30.

B30 kg·m/s, directed northeast.

C60 kg·m/s, directed northwest.

DAbout 42.4 kg·m/s, directed southeast.

Solution & Explanation:Let east be +x and north be +y. Initial p = (0, 30) and final p = (30, 0), so Δp = (30, -30). Its magnitude is about 42.4 kg·m/s and it points southeast.

Problem 2Difficulty: Mastery

A sensor reports a momentum vector of (-18, 24) kg·m/s for a 6 kg object. What are the object's velocity components and direction?

A(-108, 144) m/s, toward the northwest.

B(3, -4) m/s, toward the southeast.

C(-3, 4) m/s, toward the northwest.

D(-12, 18) m/s, toward the northwest.

Solution & Explanation:Divide momentum by mass: v = (-18/6, 24/6) = (-3, 4) m/s. Negative x and positive y indicate northwest motion.

Problem 3Difficulty: Mastery

A puck's momentum changes from (3, 4) kg·m/s to (-9, 4) kg·m/s after bouncing from a vertical wall. What is the change in momentum?

A(12, 0) kg·m/s.

B(-12, 0) kg·m/s.

C(-6, 8) kg·m/s.

D(0, -12) kg·m/s.

Solution & Explanation:The y-component stays 4 kg·m/s, while the x-component changes from 3 to -9. Δp = (-9, 4) - (3, 4) = (-12, 0) kg·m/s.
