Answer:
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
