The HARP (High-Altitude Research Project) gun can fire an 86.00 kg projectile containing scientific instruments straight up to an altitude of 185 km. If we pretend there is no air resistance, what muzzle speed is required to attain this altitude? How long does the projectile remain at a height in excess of 1.00 x 10²km, the height of interest for high-altitude research? (Answer in SI units)
