Please help me with the following questions. I don't understand and it's asking to input the answer with "correct significant digits". Please just show me the proof to prove your answer is correct and then at the end just tell me EXACTLY what to type in the box.

Q1.

An object is thrown into the air with a velocity of 25.0 m/s at an angle of 32.0 to the horizontal. How far with this object travel horizontally ? Input your answer with the correct significant digits. Do not include units. Answer:An object is projected from the top of a building at an angle of 28 at a velocity of 15 m/s. If the object hits the ground 32 m from the base of the building, how high is the building ? Input the answer with correct significant digits. Do not include units. Answer:An object is thrown up at an angle, at a velocity of 28.0 m/s. This object reached a maximum vertical displacement of 19.5 m, at what angle from the horizontal was it thrown ? Input your answer with correct significant digits Answer:A football player kicks a football at an angle of 33" with the horizontal at a velocity of 24 m/s. Assuming a player who is to receive (catch) this ball is 49 m from the ball when it is kicked (and in the direction of the kick). How fast must the receiver run to catch the ball before it hits the ground ? Input your answer with correct significant digits
