A bullet is fired straight up with a muzzle velocity of 1200 ft/s. How high does the bullet go, neglecting any air resistance?
gravitational acceleration is 32 ft/s^2
so the bullet rises for ... (1200 ft/s) / (32 ft/s^2) ... sec
during the rise time, the average velocity is ... (1200 ft/s + 0 ft/s) / 2
the height is ... velocity * time = ?
