(a) an object of mass 0.2 kg is hung from a spring whose spring constant is 80 n/m and allowed to oscillate. the object is subject to a resistive force given by -bv, wherc u is the objects velocity in metres pcr second (i) if the damped frequency is 0.995 of the undamped frequcncy, what is the value of the damping constant b? (6) (ii) by what factor is the amplitude of the oscillation reduced after 4 complcte cycles?

the results is a decrease in air temperature with an increase of altitude.

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.
