Answer 1

So the body cannot move is the answer of your question

Answer 2

here p1 is 12kgm/s

force is 20N

time is 5sec

➡️according to Newton second law of motion

rate of change of momentum is directly proportional to force applied

dp/dt=kf (k is constant of proportionality, k=1)

p/5=20

p=20*5

p=100kgm/s
