Question

An object of mass 20 kg is raised vertically through a distance of 8.0 m above ground level. Using g=10 m/s^2 what is the potential energy of this object at this position? A.)160 Nn B.)1600 Nm C.)160 N/m D.)1600 N/m

Answer 1

The formula for finding potential energy is: f= m*g*h. where "m" is mass of the object in question. "g" is the gravitational acceleration."h" is height above the ground. So, if we put in the values:
$20*10*8$
$1600$ joules
