Solve the all parts of given question:
Question: A small rock is thrown from the roof of the building with a speed of 20 m/s at an angle of 37 degrees above the horizontal. The rock strikes the ground 3.5 s after it is thrown.
Part I: What is the horizontal distance from the base of the building to the point where the rock strikes the ground?
Part II: What is the height of the building?
Part III: What is the magnitude of the resultant velocity of the rock ( the rock's speed) just before it strikes the ground?
Please write the step and answer.
