Physics question on distance and other things?

1. A gun weighing 26kg fired a 2g bullet which has a recoil speed of 0.65 m/s. Assume speed of bullet and recoil are horizontal, what is the velcity of the bullet when it is fired?

2. If it takes 0.175s for the spy to prepare to catch the bullet will he be able to catch it? Assume the air resistence decelerates the bullet at 0.12 m/s^2 and the distance between the agent and the spy is 7.5m.

3. Agent kicked the bag at an angle of 40deg at a height of 0.97 m. The bag travels as velocity of 20m/s. How far will it travel after hitting the ground? (Neglecting friction)

4) a) based on your data from #3 how long will it take for the bag to fall on the ground?

B) lets say both people can cover the distance of 10 m in 1.5s will they be able to catch the bag before it falls?

Theres just too much physics homework i've got and my brain can't function from the damage. i don't know how i would figure out the question.

1) conservation of momentum so 26 x 0.65 = 0.002 x speed..... speed = 26x0.65/0.002 = 8450m/s (8km in a second !! who made this qn lol)

2) Losing only 0.12m/s of speed every second would hardly take any speed off a bullet over 7.5metres.. and in 0.175s the bullet would travel 0.175 x 8450m... a very long way past the clown !!

3) If there is no friction it will slide forever as it has forward motion (as well as downward which was impulse cancelled by the Earth)
4a) just consider vertical motion... x=-.97m V=20sin(40) a=-9.81 find t... use x=Vt+0.5t^2
-0.97 = 14.9t +5t^2
5t^2 + 14.9t +0.97 = 0
trial and error t on a spread sheet
I get t is about secs to hit the floor
