3. Consider a freely falling object.
a. What is the acceleration (in m/s2) after 5 seconds of fall?
b. What is the acceleration (in m/s2) after 10 seconds of fall?
c. What is the velocity (in m/s) after 5 seconds of fall?
d. What is the velocity (in m/s) of 10 seconds of fall?
a. the acceleration is a function of gravity...it is essentially constant
b. see a.
gravitational acceleration (g) is 9.8 m/s^2
... for every second you fall, you go 9.8 m/s faster
for c. and d. , multiply the free-fall time by the acceleration (g)
