- with the device starting from a still position (0 m/s), you drop it, allowing gravity to accelerate it towards the ground at 9.8 m/s2. assuming it takes 1.5 seconds for the device to hit the ground, what is it’s velocity? [v = at]

- momentum is defined as mass velocity [p = mv]. calculate the momentum of the device just before it hits the ground using the velocity you calculated in the last question.

- the equation pe = mg* using h, what is the potential energy (pe) of the device before it is dropped? [remember, h = height, m = mass, g = acceleration due to gravity]

- what is the kinetic energy that the device contains immediately before it hits the ground? [ke = ½mv2]

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?
