Which statement is TRUE of a block of stone of mass m, with zero momentum?
A
The acceleration of the stone is non-uniform
B
The stone is stationary
C
The stone moves at a constant velocity
D
The stone moves with maximum velocity
E
The stone moves with minimum velocity.
Verified Correct Answer: B.
Physical Principles & Numerical Solution
