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

0.2 m/s^2

Explanation:

Maximum distance, h = 19.5 m

initial speed, u = 2.80 m/s

final speed, v = 0 m/s

Let the gravitational acceleration is a.

Use third equation of motion

a = 0.2 m/s^2

Thus the gravitational acceleration on the exoplanet is 0.2 m/s^2

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

answer: b.
