A 1000 kg car and a 2000 kg truck have the same momentum. The car's kinetic energy compared with the truck's is
A.twice as large
B.the same
C.half as large
D.four times as large
Explanation
Core Concept
K = p²/2m: at equal p, lighter mass gives more kinetic energy — the car (half the mass) has twice as much.
Correct Answer
Atwice as large
