Question

what is the potentual energy of 7 kg object, 12 m off the ground?​

Answer 1

Answer:

823.2 J

Explanation:

PE = mgh

= (7 kg) (9.8 m/s^2) (12 m)

= 823.2 J

Answer 2

Answer:

Required Answer:-

Mass=m=7kg

Height=h=12m

Gravitational force=g=10m/s^2

• As we know that

${\boxed{\sf Potential\:energy{}_{(P.E)}=mgh}}$

• Substitute the values

${:}\longmapsto$$\sf P.E=7×12×10$

${:}\longmapsto$$\sf P.E=84×10$

${:}\longmapsto$$\sf Potential\:energy=840Joule$
