1)How do I find the time that the object is in the air?

2)The horizontal distance of the object?

Could someone help me out?

**Damon**, Sunday, January 4, 2009 at 7:23pmN means Newtons and is FORCE, in this case of gravity (the "weight").

The mass is in KILOGRAMS

and the force 49 N = m g = m (9.8) approximately on earth.

HOWEVER - luckily in this problem all of that matters not at all. It does not matter what the mass or weight is at all. It accelerates downward at 9.8 m/s^2 and keeps going at 20 m/s horizontally.

distance down = (1/2)(9.8) t^2

300 = 4.9 t^2

t = 7.82 seconds in the air

now multiply that by 20.0 m/s to find the horizontal distance.

(Notice that the bomb hits right under the plane if the plane keeps going at 20 m/s straight. Always bank and climb after dropping bombs.)
