2. In 1966, a special research cannon built in Arizona shot a projectile to a height of 180 km above Earth’s surface. The potential energy associated with the projectile when its altitude was 10.0 percent of the maximum height was 1.48 × 107 J. What was the projectile’s mass? Assume that constant free-fall acceleration at this altitude is the same as at sea level.
