Below are sample questions representative of the exercises included on this worksheet and related 9.50 Momentum and Collision Safety skill assessments:

Problem 1Difficulty: Mastery

A prototype restraint stops the same dummy from the same speed in 0.24 s instead of 0.08 s. Which argument best uses impulse and collision time?

AThe momentum change is the same, so tripling the stopping time lowers average force to about one-third.

BThe impulse is zero because the restraint is softer.

CThe longer time means the dummy has three times more momentum before impact.

DThe shorter stopping time is safer because it finishes the collision faster.

Solution & Explanation:The dummy's change in momentum is set by its initial and final velocities. For the same change in momentum, average force is inversely proportional to stopping time.

Problem 2Difficulty: Mastery

Use the cart-pair diagram. Which pair has equal momentum magnitudes but different kinetic energies?

APair A

BPair C

CPair D

DPair B

Solution & Explanation:Pair A momenta are both 12 kg*m/s, but the lighter faster cart has greater kinetic energy. Equal momentum does not require equal kinetic energy.

Problem 3Difficulty: Mastery

A seat-belt load limiter allows the belt to extend slightly during a crash while still restraining the passenger. What is the intended collision-safety effect?

AIt can increase stopping time and reduce peak force while still changing the passenger's momentum to zero.

BIt eliminates the force needed to stop the passenger.

CIt increases peak force by making the stopping time shorter.

DIt makes the passenger's momentum remain unchanged during the crash.

Solution & Explanation:The passenger still needs a momentum change to stop. A controlled extension can spread that change over more time, lowering peak force.
