Answer:
Correct answer: 2) 2p
Explanation:
Momentum
Momentum is a measurement of mass in motion or how much mass is in how much motion. The symbol for momentum is p and is defined as:
p = m . v
Where m is the mass of the object and v is the speed. Note this is the scalar version of the formula because both p and v are vectors.
Suppose the mass of the object is doubled to 2m, then the new momentum is:
p' = (2m) . v = 2 m . v
Or, equivalently:
p' = 2p
Correct answer: 2) 2p
