A body is dropped from the rooftop of the building.The body reaches the ground at t= 4.05 from the point of release.how tall is the building?what is the speed of the body just before it reaches the ground?

    The symbol t is usually not used to denote distance. It is used for time. Did you copy the problem correctly? What are the dimensions that go with the number 4.05?

    i copied the problem correctly sir :)

    The problem would make sense if it said the body reaches the ground 4.05 seconds after it is dropped. If it is really the way you said, with no dimensions after the number 4.05, you should be learning physics somewhere else.
