Answer:
Explanation:
If no one can see it because the lights were out. Did the flea really jump?
What do you want here?
Max height (2.2sin21)²/ 2(9.8) = 3.2 cm
Time of flight 2(2.2sin21)/ (9.8) = 0.16 s
distance of flight (2.2cos21)(0.16) = 33 cm
Momentum (in terms of classical mechanics) is defined as p = m*v, where m is the mass and v is the velocity.
In scientific inquiry, hypothesis acts as the road map that guide the researcher and show him how to go about his scientific investigation. Hypothesis provides a testable explanation for an observation and serves as the starting point for the scientific investigation.
