Abackpack has a mass of 8kg. it is lifted and given 54.9 j of gravitational potential energy. how high is it lifted? acceration due to gravity is g=9.8m/s2

The height of the bag pack is 0.7 m.

The gravitational potential energy is given by the formula

P=mgh

Now plugging the values in the above equation to calculate the height of the bag pack

54.9=8*9.81*h

h=0.7 m

Therefore the bag pack is lifted to the height of 0.7 m.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
