Asoccer ball is kicked from the ground, and its height in meters above ground is modeled by the function h(t) = -4.9t2 + 19.6t, where t represents the time in seconds after the ball is kicked. how long is the ball in the air?

double the distance = divide strength by 4

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.
