Suppose you are an intrepid interplanetary explorer and you've landed on the remote planet, Gorzag. Your task is to determine the free-fall acceleration on the surface of Gorzag, which has no atmosphere. All you have is a space rock, a stop watch, and a laser range finder (a tool to measure distance). You find a nearby cliff and make the following measurements: the height of the cliff is 55m, and when you drop the rock off the cliff it takes 40s for the rock to hit the ground below. Show your work.

PLEASE WORK ON THE SECOND QUESTION(Question B). Problem: As the first human astronaut to land on a distant planet, you are standing on the edge of a small cliff. You toss a small experiment apparatus straight up in the air and it reaches a maximum height of 3.0m above the cliff. The apparatus then falls to the bottom of the cliff, landing a distance 10 m below its initial position. A) Given that the acceleration due to gravity on the exoplanet is a=−5.6j^  m/s^2 {REFER TO ONE OF THE PICTURE}, how long did it take for the apparatus to get from the top of its trajectory to the bottom of the cliff? The coordinate system is set up such that "up" is in the +j^ direction.   Answer a): 2.2 seconds.   ****B)Suppose the time between the apparatus leaving your hand and landing on the ground was measured to be t=4.80s. What was the velocity of the apparatus leaving your hand?

A space shuttle lands on a distant planet where the gravitational acceleration is 2.0 ( We do not know thelocal units of length and time , but they are consistent throughout the problem). The shuttle coasts along aleve, frictionless plane with a speed of 6.0. It then coasts up a frictionless ramp of height 5.0 and angle 0f 30°.After a brief ballistic flight, it lands a distance S from the ramp. Solve for S in local units of length. Assume theshuttle is small compared to the local length unit and that all atmospheric effects are negligible. Use x and y  components.

Different satellites orbit the earth with a vast range of altitudes, from just a couple hundred km, all the way to tens of thousands of km above the surface. The international space station (ISS) is in a low earth orbit, just 400km above the surface (you can see it with the naked eye at sunset and sunrise as a bright, moving dot). At this altitude, the acceleration due to gravity has a value of 8.69 m/s². (Assuming that the radius of the earth is 6400km). What is the speed of the ISS? Express your answer to three significant figures and include the appropriate units. V = Part B H Submit T = μA Value Request Answer Units ? What is the orbital period (T) of the ISS in minutes?
