Question
An impulse Î change the velocity of a particle from 
to 
. kinetic energy gained by the particle is
to . kinetic energy gained by the particle is Options
A.
Î .( + )
Î .( + )B.Î .( - )
Î .( - )C.Î .( - )
- )D.Î .( + )
+ )Solution
ᐃKE = 
mv22 -
mv12
=
m ( - ).ᐃKE = mv22 - mv12
=m ( - ).( + ) = 
Î.( + ).
mv22 - mv12=
m ( - ).ᐃKE = mv22 - mv12=
m ( - ).( + ) = Î.( + ).Create a free account to view solution
