13. momentum is an object’s mass times velocity. which has more momentum? a paper airplane with a mass of 10g flying at a velocity of 4m/s, or a real airplane that is parked on a runway with a mass of 1000kg and a velocity of 0m/s

For this case we must convert 26 seconds to hours,

By definition we have to:

1 hour equals 3600 seconds.

So, if we propose a rule of three we have:

1 hour ----------> 3600 seconds

x ------------------> 26 seconds

Where the variable "x" represents the number of hours equivalent to 26 seconds:

Thus, 26 seconds equals approximately 0.0072 hours.

0.0072 hours
