What is the potential energy of a 2kg plant that is on a windowsill 1.3m high?
Marysya12 [62]

Answer:

P.E = 25.48 Joule

Explanation:

Here,

mass (m) = 2kg

height (h) = 1.3m

g = 9.8m/s^2

P.E = mgh

= (2) (9.8) (1.3)

P.E = 25.48 Joule

Thus, the potential energy of a 2kg plant that is on a windowsill 1.3m high is 25.48 Joule

Answer: The answer is C.) 25 m/s^2.

Explanation: If you input 5 as s, you would have to use the exponent 2.  This means that you have to multiply 5 by 5.  5 x 5= 25.  

Edit: Also, because the surface is frictionless, it will make the object go faster too.  Nothing can really slow it down unless something blocks it.
