a
20.0kg ms-1
b
10.0kg ms-1
c
5.0kg ms-1
d
1.3kg ms-1
e
0.0kg ms-1.

their explanation is actually correct
since the ball rebounds, v(final velocity) becomes -2, where u(starting velocity )is 2, abd our m(mass)=5
impulse =m(v-u)
=5x(2-(-2))
=5x(4)
=20kgms^-1
hope u are all clear now ??

My school you're the worst in explanation of things
I dunno if you're explaining for yourself alone or for people who don't understand what they failed 🤷
