How high will the bullet go?

Question

A 0.040 kg bullet is fired straight up with a velocity of 250 m/s. If 1,000 J of energy is dissipated by air resistance, how high will the bullet go?

Answer 1

Force with which bullet moves up = ma

                   = 0.040*9.81

                   =3.924 N

Using the famous equation of “work= force * distance d”,

         1,000= 3.924d

                      From which                d =254.842 m

the bullet will move 254.842 m up
