This is based off newton’s though experiment. only information really provided is:
the projectiles mass is not needed.
the projectiles must be launched on the horizontal plane.
the earth drops 8 inches for every mile traveled.
the acceleration due to gravity is 9.82 meters per second squared.
ignore air resistance.
1.how fast does an object need to travel to stay in orbit for one second?
2. how fast does an object need to travel to stay in orbit for two seconds?
3. how fast does an object need to travel to stay in orbit for three seconds?
4. you may have noticed that the object needs to keep going faster and faster to stay in orbit. what is the average acceleration needed for the object to stay in orbit from 1-3 seconds?
5. in the real world, orbiting objects such as satellites do not need to be constantly accelerating. what is different about real-world satellites and the theoretical satellites?

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)

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
