On the moon, a feather will fall to the ground at the same rate as a heavy stone. Suppose a feather is dropped from a height of 40 m above the surface of the moon. Then its height in s (in meters) above the ground after t seconds is s=40−0.8t2. Determine the velocity and acceleration of the feather the moment it strikes the surface of the moon.

A parachutist jumps out of an airplane and accelerates with gravity to a maximum velocity of 68.6 m/s in 7.00 seconds. She then pulls the parachute cord and after a 3.3-second constant deceleration, descends at 10.5 m/s for 9.2∗1019.2∗101seconds, reaching the ground. From what height did the parachutist jump? answer in meters. (assume g = 9.8 ?/?2m/s2 )

You are exploring a planet and drop a small rock from the edge of a cliff. In coordinates where the +y direction is downward and neglecting air resistance, the vertical displacement of an object released from rest is given by y − y0 = 1/2gplanett2, where gplanet is the acceleration due to gravity on the planet. You measure t in seconds for several values of y − y0 in meters and plot your data with t2 on the vertical axis and y − y0 on the horizontal axis. Your data is fit closely by a straight line that has slope 0.300 s2/m. Based on your data, what is the value of gplanet?
