An object falls from a position of rest and reaches an instantaneous speed of 9 m/s.
How far will it have dropped? The acceler-
ation of gravity is 9.8 m/s?.
Answer in units of m.

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

What happens when you slowly pulled the carboard?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
