Dexter needs to monitor the movement of a rover vehicle on mars for one year. which technologies should dexter use for tracking purposes? check all that apply. telescopes that show where the rover vehicle is located satellites that collect information about rover vehicle distance space stations that store real-time data about rover vehicle speed computer simulations that model how long it takes the rover to get to mars doppler radar that records information about weather the rover is exposed to

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
