Impulse = Ft = (m)(delta v)
delta v = change in velocity = velocity final - velocity initial.
= -22m/s - +18m/s = -40m/s.
mdeltav = (0.40kg)(-40m/s) = -16kgm/s or -16Ns.
Explanation:
225=m (2.20m/s2 which give m=16kg I used newtons second law to fins the required average force
Answer is A of course lol Fire needs oxygen as an essential fuel to burn.
Melting freezing and boiling are molecular changes
Answer:
I can explain it using the law of force
or Newton's law of motion
