An aeroplane is preparing to land from an initial height of 2000 meters. Its initial velocity is 200 m s and the angle of decent is −30◦ . If the plane is able to apply a constant horizontal deceleration a0, what does a0 need to be in order for the plane to reach a horizontal velocity of 75 m s upon touchdown (assume there is no additional vertical acceleration outside of gravity)?

A bullet shot from a small firearm has an initial velocity v0 of 52 m/s at an angle theta = 42 with respect to the horizontal. At the maximum trajectory (max height), we observe that, the bullet explodes into two small pieces both of which are of equal mass. One fragment  immediately after the explosion is therefore zero m/s and it falls vertically. How long (in seconds) does it take the shell to reach this point trajectory (max height)? What is...
