Abolt falls off an airplane high above the ground. how far does the bolt have to fall before its speed reaches 100m/s (about 200 miles per hour)? you should ignore air friction in your calculation.

Aspectroscope breaks light up into its colors, allowing scientists to analyze light from the solar system and universe. by studying the spectral line patterns, widths, strengths and positions, scientists can determine the speed, position, and of celestial bodies. a) age b) origin c) rotation d) temperature
