84. Calvin uses a slingshot to launch an orange straight up in the air to see what will happen. The distance in feet be- tween the orange and the ground after t seconds is given by the equation s(t) = –16t² + 90t +5. Use this equation to answer the following questions: (a) What is the initial height of the orange? What is the initial velocity of the orange? What is the initial ac- celeration of the orange? (b) What is the maximum height of the orange? (c) When will the orange hit the ground?

3- a rocket launched from a height h with initial velocity 100 m/s and it make angly 30 with the horizon , and its fall after 1000 m , what is the hight h and what is the flight time ?
A rocket is fired at a speed of 83.0m/s from ground level, at an angle of 66.0degrees above the horizontal. The rocket is fired towards an 28.8m high wall, which is located 25.0m away. The rocket attains its launch speed in a neglibly short period of time, after which its engines shut down and the rocket coasts. By how much time does the rocket clear the top of the wall?

In Dover, Delaware, a post-Halloween traditionis “Punkin Chunkin,” in which contestants build cannons, catapults, trebuchets, and other devices to launch pumpkins and compete for the greatest distance. Though hard to believe, pumpkinshave been projected a distance of 4694 feet in this contest. What isthe minimum initial speed needed for such a shot?
A football receiver running straight downfield at 5.50 m/s is 10.0 m in front of the quarterback when a pass is thrown downfield at 25.0 above the horizon (Fig. P3.58). If the receiver never changes speed and the ball is caught at the same height from which it was thrown, find (a) the footballs initial speed, (b) the amount of time the football spends in the air, and (c) the distance between the quarterback and the receiver when the catch is made.
