Astronauts on our moon must function with an acceleration due to gravity of 0.170g. a.) if an astronaut can throw a certain wrench 15.0m vertically upward on earth, how high could he throw it on our moon if he gives it the same starting speed in both places? the answer to this one is 88.2m b.)how much longer would it be in motion (going up and coming down) on the moon than on earth? i just need on part b, if you me and show me all the steps.

88.23525 m

17.07596 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity

On Earth

On Moon

The wrench could be thrown a distance of 88.23525 m on the Moon.

On Earth

The time the wrench is in the air on Earth is 1.74874+1.74874 = 3.49748 s

On Moon

The time the wrench is in the air on Earth is 10.28672+10.28672 = 20.57344 s

The difference in time is 20.57344-3.49748 = 17.07596 seconds

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:

formula.

example:

given values:

mass = 0.3 kg.

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
