Two seconds after a projectile is fired from a gun, located on the ground, it has a velocity equal to: v = 30i +20.4j, m/s

1.) Determine the initial speed of the projectile

2.) At what angle is the projectile fired?

3.) How long does it take the projectile to reach the highest point in its trajectory?

4.) What is the speed of the projectile at it's highest point in its trajectory?

5.) What is the magnitude of the projectile's velocity just before it hits the ground?

A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. The same projectile was then fired in the same way toward a wall that is a horizontal distance (d) m from where the projectile was fired, and the projectile (as it's going down) hit the wall. If the wall were slightly farther from where the projectile was launched (the projectile...

A projectile is fired from a gun on the ground angled up at 6 degrees. The gun will give the projectile all of the necesary orbital velocity. I need to know the delta-v that a thruster on the projectile would need for orbit insertion. a) for a 300km circular orbit b) for an elliptical orbit with a perigee of 300km, any apogee is ok. No inclination change. Initial and final inclination is 15 degrees. Total projectile mass is 500kg.
