1 pts Question 5 5) A ball is launched straight upwards at 11 m/s from the side of a building which is 134 meters above the ground. At the exact same time, a projectile is launched from the ground (the base of the building). The projectile is 39 meters from the base of the building. With what speed does the projectile need to be launched, in m/s, such that the it strikes the other ball, 16 meters above the ground?

A 736-lb object is launched from the ground with an initial upward velocity of 60 ft/sec. The atmosphere resists the motion of the object with a force of 3 lb for each ft/sec of speed. Assuming that the only other force acting on the object is gravity, find the time it takes for the object to reach its maximum height:
