2. An object is shot straight upward from sea level with an initial velocity of 750 ft/sec. a. Assuming that gravity is the only force acting on the object, give an upper estimate for its velocity after 5 sec have elapsed. Use g= 32 ft/sec- for the gravitational acceleration. b.Using At=1 sec, find a lower estimate for the height attained after 5 sec. a. The upper estimate for the velocity after 5 sec is ft/sec. b. The lower estimate for the height after 5 sec is ft.
