I'm taking a college level physics class, and I'm just a wee bit stuck on the following problems. It's an online course so I don't really have a teacher for it I could ask my High School's Science Teacher, but I don't have any classes with him and really don't want to have to show up before or after school to ask him. Classical Mechanics never really was my strong suit; I'm more of a Quantum kind of guy.
Question 1: Harry accidentally falls out of a helicopter that is traveling at 100 m/s. He plunges into a swimming pool 2 seconds later. Assuming no air resistance, what was the horizontal distance between Harry and the swimming pool when he fell from the helicopter?
Question 2: A boy on a 20 m tall tower throws a ball and 60 m horizontal from the base of the tower the ball lands on the ground. At what speed in m/s was the ball thrown?
Question 3:The movie "The Gods Must Be Crazy" begins with a pilot dropping a bottle out of an airplane. It is recovered by a surprised native below, who thinks it is a message from the gods. If The plane from which the bottle was dropped was flying at an altitude of 500m, and the bottle lands 400m horizontally from the initial dropping point, how fast was the plane flying when the bottle was released.
