An object is dropped from a tower, 1024 ft above the ground. The object's height above ground i seconds after the fall is s(t) = 1024 - 1612. Determine the velocity and acceleration of the object the moment it reaches the ground. ft/s. The velocity of the object the moment it reaches the ground is (Simplify your answer.) The acceleration of the object the moment it reaches the ground is fus2 (Simplify your answer.)

An object is projected with initial speed v0 from the edge of the roof of a building that has height H. The initial velocity of the object makes an angle α0 with the horizontal. Neglect air resistance. A) If α0 is 90∘, so that the object is thrown straight up (but misses the roof on the way down), what is the speed v of the object just before it strikes the ground? Express your answer in terms of some or...
