A) \[3.5J~\]
B) \[5.5J~\]
C) \[2.5J~\]
D) \[4.5J~\]
Correct Answer: D
Solution :
: The kinetic energy K and momentum p of a body are related as \[K=\frac{{{P}^{2}}}{2m}\]where m is the mass of the Here, \[p=6N\,s,\,m=4kg\] \[\therefore \] \[K=\frac{{{(6\,N\,s)}^{2}}}{2(4\,kg)}=4.5J\]You need to login to perform this action.
