A ball is thrown vertically upwards with a velocity of 12 m/s. Is reaches to a maximum height and falls directly to the ground. How long (in s) was the ball in air?.

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.

this could be newton#'s law of cooling. the cooling curve is exponential

i think the answer is a and b

i wish you luck

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
