A halfback (m = 80 kg), a tight end (m = 100 kg), and a lineman (m = 120 kg) are running down the football field. Consider their ticker tape patterns below. The lineman's velocity is 3 m/s (right). The tight end's velocity is m/s and the halfback's velocity is m/s. Which player has the greatest momentum and how much momentum does he have? Explain.

Speed of Halfback is 9 m/s

Speed of Tight end is 6 m/s

greatest momentum is for Halfback which is equal to 720 kg m/s

Explanation:

As we know that the ticker tape diagram is shown in the figure

Here each tick is regarding the displacement in 1 s

the velocity of lineman is given as 3 m/s

So here we can see that position of lineman after 2 s is same as position of tightend after 1 s

So displacement of tightend after t = 1 s is given as d = 3(2) = 6 m

so velocity of tightend is v = 6 m/s

Similarly the position of lineman after 3 s is same as position of halfback after 1 s

So displacement of halfback after t = 1 s is given as d = 3(3) = 9 m

so velocity of halfback is v = 9 m/s

Now momentum of lineman is given as

momentum of halfback is given as

momentum of tightend is given as

So greatest momentum is for Halfback which is equal to 720 kg m/s

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
