Describe an experiment to measure the acceleration due to gravity in a school laboratory using a helical spring. Your account should include a diagram, observations, precautions, and how you would use your observation to reach a conclusion.
A dart is loaded into a spring-loaded toy dart gun by pushing the spring in by a distance x. For the next loading, the spring is compressed a distance of 2x. How much faster does the second dart leave the gun compared with the first? Explain your answer using the appropriate equations.
A 50.0 kg man standing on a spring scale takes a descending elevator ride (DOWNWARD). Starting from the rest, the elevator descends, attaining a maximum speed of 8.0 m/s in 4.0 seconds. Then the elevator travels with this constant speed of 8.0 m/s for 10.0 seconds. Lastly, it takes the elevator 2.0 second to make a complete stop. Based on the information above, answer the questions below:
(Hint: Drawing pictures would help you understand the 3 legs of this elevator ride. Since the elevator is descending, going down, it is more convenient to chose downward direction as + direction. Please pay attention to the sign of each physical quantity, such as velocity, acceleration, and displacement, etc.
Useful formula: v = vi + a×t, or
d = v0×t + ½ a × t2,
Weight = mg,
Newotn’s 2nd Law: Net force Fnet = ma
