Question

Recall that the formula for momentum is: P=mv Which of the following correctly shows momentum being calculated? (1 point) Responses 14 kg*/s=(9 kg) (5 m/s)s 14 kg * / s = ( 9 kg ) ( 5 m / s ) s 45 kg*m/s=(9 kg) (5 m/s) 45 kg * m / s = ( 9 kg ) ( 5 m / s ) 4 kg*m/s=(9 kg) (5 m/s) 4 kg * m / s = ( 9 kg ) ( 5 m / s ) 45 N=(9 kg) (5 m/s)

Answer 1

To correctly show momentum being calculated according to the formula \( P = mv \), we need to ensure that the units are consistent and the calculations are accurate.

Given the following options, we can evaluate:

1. 14 kg/s=(9 kg) (5 m/s)*: This equation is wrong both in units and calculation.

2. 14 kg * / s = (9 kg) (5 m / s): This equation is also wrong due to the incorrect calculation.

3. 45 kg*m/s=(9 kg) (5 m/s): Correct calculation and units. \( 9 , \text{kg} \times 5 , \text{m/s} = 45 , \text{kg*m/s} \).

4. 45 kg * m / s = ( 9 kg ) ( 5 m / s): This is equivalent to option 3; incorrect formatting but correct calculation.

5. 4 kg*m/s=(9 kg) (5 m/s): Incorrect calculation.

6. 4 kg * m / s = ( 9 kg ) ( 5 m / s): Incorrect calculation.

7. 45 N=(9 kg) (5 m/s): Incorrect unit (N stands for Newton, which is not appropriate here as we're calculating momentum).

Based on the above analysis, the correct option showing momentum being calculated is:

45 kg*m/s=(9 kg) (5 m/s).
