Ahuman expedition lands on an exoplanet. one of the explorers is able to jump a maximum distance of 19.5 m with an initial speed of 2.80 m/s. find the gravitational acceleration on the surface of the exoplanet. assume the planet has a negligible atmosphere.

Acceleration,

Explanation:

It is given that,

Initial speed of the explorers, u = 2.8 m/s

Finally it lands, v = 0

Maximum distance, x = 19.5 m

We need to find the gravitational acceleration on the surface of the exoplanet. Let a is the acceleration. It can be calculated using third equation of motion as :

So, the gravitational acceleration on the surface of the exoplanet is . Minus sign shows that the acceleration is acting in downward direction. Hence, this is the required solution.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

it would be c. predictability
