The next few questions challenge you to figure out the acceleration due to gravity ( g ) on various hypothetical alien planets. On Planet #1, you drop a stone from rest, 82.8 m above the ground, and the stone hits the ground 3.21 s later. What is the value of g on Planet #1?     25.79 m/s^2     51.59 m/s^2     16.07 m/s^2     8.04 m/s^2

suzie is standing at the top of a cliff.  she says if she drops a heavy rock off the cliff it is 110 meters high. the rock starts from rest, and gravity accelerates the rock at 9.81 m/s^2 downwars.   how long it should take for the rock to fall 110meters?

OK, this is the last time for one of these crazy adventures. THIS time, though, there is a window in the floor, and you can see that you re in a rocket which has just taken off from the surface of an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 9.60 m/s^2. When you drop a ball from a height of 1.20 m, it hits the floor 0.362 s later. What is the value of g for the alien world below you?     16.5 m/s^2     8.7 m/s^2     28.1 m/s^2     18.4 m/s^2

An object is thrown straight up on planet X with an initial speed of 45 m/s. What is the acceleration of gravity on this planet (in m/s2 ), if 3 seconds later the object gets to the peak of its path. 5 10 15 20 none of these

OK, yet another strange awakening in a room with no windows. This time you drop a ball from a height of 1.67 m and it hits the floor 0.292 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rocket s acceleration to be? 1 58.8 m/s^2 29.4 m/s^2 3 49.0 m/s^2 4 39.2 m/s^2

The next few questions challenge you to figure out the acceleration due to gravity ( g ) on various hypothetical alien planets. On Planet #1, you drop a stone from rest, 76.1 m above the ground, and the stone hits the ground 6.17 s later. What is the value of g on Planet #1?     24.67 m/s^2     4.00 m/s^2     2.00 m/s^2     12.33 m/s^2

This time you drop a ball from a height of 1.82 m and it hits the floor 0.365 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rocket s acceleration to be?     27.3 m/s^2     33.3 m/s^2     17.5 m/s^2     37.1 m/s^2

Suppose that in the future humans can travel to different earth like planets within our galaxy. You take a trip to a new planet with a different gravitational acceleration than earth. To test this gravitational acceleration, you decide to drop a ball a distance of 2 meters. You measure how long it takes the ball to fall 2.0 meter multiple times and take an average. The average drop time is 0.52 seconds. What is the approximate magnitude of the gravitational acceleration of the planet (in units of m/s squared)?

An astronaut exploring a distant solar system lands on a planet with a gravitational acceleration of 7.46 m/s2. What is the maximum height an astronaut could reach when jumping straight up starting with an initial speed of 1.80 m/s?
