Question
Questions: The planet Tralfamador is a planet of mass Mand Radius R, and very thin atmosphere (neglect airresistance). A magnetic rail gun has been mounted on the surface ofTralfamador at the North pole. A projectile of mass m isfired from the magnetic rail gun with an unknown speedvo at an unknown angle with repect to thelock horizontal. The projectile is observed to rise to a maximumheight above the surface of 1/4 Radius. At this maximum height theprojectile has a speed of 75.0 m/s1) If M = 1.5 x 1020 kg( so that GM =1.0 x1010 Nm2/kg) and R = 200 km, findvo in m/s.
2. Find the launch angle
