Which object is accelerating downward at the slowest rate?
a bird's feather falling from a tree branch to the ground
a rock dropped from the roof of a tall building
a baseball just after it is struck for a home run
a model rocket falling to the ground after it has reached its maximum height

it should be -8.6 cm hope this out

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

unbalanced force

explanation:

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:
