A bullet is fired in a horizontal direction with a muzzle velocity of 300m/s.in the absence of air resistance,how far will it have droppped in travelling a horizontal distance of 20m.

• physics -

how long did it take to get 20 m?

time=distance/velocity=20/300 sec

how far did it drop?
distance=1/2 g time^2

• economics -

80ma
