Question

pls let me know the ans of those 3 questions please​

Answer 1

Answer:

1.area of f-t graph gives impulse.

hence from the graph impulse(j)=1/2×100×(10-1)

=450kgm/s^2

2.impulse is same as momentum hence we can say that j=mv

                                                                                             450=(200×10^-3)v

                                                                                        v=2250m/s.

3.Ft=j

same time and same impulse as given implies same force .hence the force is as in first graph 100N
