A 110 kg football player runs at 8.00 m/s. What is the magnitude of his momentum?
A88.0 kg m/s
B880 kg m/s
C8800 kg m/s
D13.75 kg m/s
Answer & Solution
Correct answer: B. 880 kg m/s
1. Momentum is calculated as p equals m times v.
2. Substituting the given values, p equals (110 kg)(8.00 m/s).
3. That multiplication gives 880 kg m/s.
4. 88.0 kg m/s is off by a factor of ten, and 8800 kg m/s is off by a factor of ten in the other direction.
5. 13.75 kg m/s instead comes from dividing mass by velocity rather than multiplying them.
