What is the acceleration of a penny as it falls if it is dropped from rest and hits the ground 3 seconds later at a speed of 29.4 m/s?

answer; /// the above statement is (true);

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

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.
