Answer:
a).p=15.67kg*m/s
b). F=7.83N
Explanation:
change in momentum is the subtraction from "after momentum" of the "before momentum" as momentum is a vector quantity this is a vector subtraction.
initial momentum of ball
m1v1 = (0.145)(44.0) = 6.38 kg-m/s
after momentum
m1v2 = (0.145)(64.0) = 9.28 kg-m/s
since these momentums are 180° opposite one must be called negative so their difference
6.38+9.28= 15.67 kg-m/s
change in momentum = 15.67 kg-m/s ANS a1
Impulse = change in momenutm = 15.67 ANS a2
b)
Impulse =Favg*t
I=(2.00)Favg
Impulse from (a2) = 15.67
Favg = 15.67/2.00 =
F= 7.83 N
The type of organism is an Archaea. Archaea are organisms that have a cell wall but lacks a nucleus. It has a hydrothermal vent which is used to live in high heat areas.

Explanation:
the inertia of an object does not make it to come to rest, this is normally caused by friction
