Question

Find the potential energy of a 40.0 kg ball lodged in a tree 10.0 m high

Answer 1

3920 Joule...

Answer 2

E=mgh

Answer 3

Thank you .

Answer 4

neva mind..

Answer 5

Would the answer be 400 J ?

Answer 6

no

Answer 7

you forgot to multiply g

Answer 8

1/2 ?

Answer 9

do you know what gravitational acceleration is?

Answer 10

Kind of yes and no .

Answer 11

Nevermind. I got it.

Answer 12

cool

Answer 13

@isadrawr..the gravitation potential energy has an expression sumthing like this:-
E=mgh
where m is mass ...h is hieght....and g is accelaration due to gravity...
g=9.8m/s near the sea level..
thus E=40*9.8*10=3920 joules...

Answer 14

Thank you .

Answer 15

E=mgh , g=9.8\[\rightarrow\]E=40*9.8*10=3920j
