The gravitational acceleration is 9.81 m/s2 here on earth at sea level. what is the gravitational acceleration at a height of 350 km above the surface of the earth, where the international space station (iss) flies? (the mass of the earth is 5.97×1024 kg, and the radius of the earth is 6370 km.) it is somewhat greater than 9.81 m/s2. it is zero, since the iss is in the state of weightlessness. it is half of 9.81 m/s2. it is somewhat less than 9.81 m/s2. it is twice of 9.81 m/s2. it is 9.81 m/s2, the same.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
