NASA sent a robotic probe to the planet Mars that collected Martian dirt that had a weight of 248g when measured back on Earth. If Mars has a gravitational force of 0.38G, what would have been
the weight when it was measured on Mars? Once you have figured out that answer, convert your
units from g to mg.
94,240 mg
94.24 mg
O 0.09424 mg
O 635.89

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
