Find the range, mean, and standard deviation of these observations:

16,4,8,14,3,10,2,24,11,7,9

An object is released from rest and falls freely. Calculate its position and velocity after
1, 5, and 10 seconds. Take the origin 0 as the elevation of the starting point, the y-axis
vertical, and the upward direction as positive.

The initial coordinate and initial velocity are both negative. The acceleration is
downward, or –32 ft/s2

position = v0t + .5at2 = –16t2
velocity = v0 + at = –32t
