Answer:

#15 kg.m//s#

Explanation:

Newton's 2nd law of motion may also be stated in terms of momentum as follows :
The resultant force acting on an object is directly proportional to the rate of change in momentum brought about.
ie. #sum vecF= (d vecp)/(dt)#, where #vecp = m vecv#.

Rearranging yields : #sum vecF dt = m d vecv#.

Thus impulse (#sum vecFdt#) equals change in momentum (#m d vec v = d vecp#)
