Angular Momentum in Linear Motion
A particle of mass m moves at a constant speed v along a straight line. The perpendicular distance from a reference point O to the particle’s path is d. At which position along its path is the particle’s angular momentum, relative to point O, a maximum?
A
When the particle is at the point of closest approach to O
B
The angular momentum is constant throughout the motion
C
When the particle is infinitely far from O
D
When the angle between r and v is 90°
