*Question 1*:
What are the units of acceleration?

Answer: meters per (seconds squared)

*Question 2*:
Joe drops a rock off the Golden Gate Bridge.
How fast is the rock moving after 2 seconds?

Answer: v = a * t v = (9.8 m/s^2) * (2 s) v = 19.6 m/s

*Question 3*:
A Corvette goes 0 - 60 mph in 4.5 seconds.
What is its average acceleration?

Answer: change in velocity avg accel = -------------------- change in time Now, 60 mph = 60 * (1609 meters)/(3600 seconds) = 26.8 m/s (26.8 m/s - 0 m/s) avg accel = -------------------- 4.5 s = 5.96 m/s^2
