During World War I, the Germans had a gun

called Big Bertha that was used to shell Paris.

The shell had an initial speed of 1.13 km/s at

an initial inclination of 42.4Degrees to the horizontal.

The acceleration of gravity is 9.8 m/s2 :

How far away did the shell hit?Answer in

units of km.

How long was it in the air?Answer in units

of s.

----------------------------------------------------------------

An autographed baseball rolls off of a 0.81 m

high desk and strikes the floor 0.28 m away

from the desk.

The acceleration of gravity is 9.81 m/s2 :

How fast was it rolling on the desk before itAnswer in units of m=s.

fell off?

2. Relevant equations

I don't know

3. The attempt at a solution

I'm not gonna try an answer and get deducted points from this online HW system. Please answer first and then we can discuss these later. Hopefully later tomorrow. I have my PSATS tomorrow and I really need to finish this up and study for em. Thanks
