Hi,

Could use some help with this question. Thanks!!!
A hammer is dropped, as an experiment, on the surface of a newly discovered planet. if it takes 0.650 s to reach the ground from a height of 0.500m, determine the value of the gravitational field (g) on this planet.

1 answer

average velocity ... va = height / time

it starts from zero velocity , so the final velocity is twice the average

the acceleration (g) is ... final velocity / time
