Question

An object of mass 8 kg is falling from a height of 5 m. It's maximum potential
energy could be

Answer 1

Answer:

formula for potential energy=mass×gravity ×height

mass=8kg

height=5m

gravity =10m/s

potential energy=8×5×10 =400

Answer 2

Answer:

m =8kg Change to m

8*5/18

40/18

m= 2.2m

h=5

g=a =10m/s or 9.8m/s

but you take 10 for easy calculation

Explanation:

PE =mgh

= 2.2 *10*5

=110J
