Answer:
[tex]\huge\boxed{\sf P.E = 130\ Joules}[/tex]
[tex]\huge\boxed{\sf P = 32.5\ Watts}[/tex]
Explanation:
Given Data:
Weight = W = 65 N
Height = h = 2 m
Time = t = 4 secs
Required:
Power = P = ?
Work Done in the form of Potential Energy = P.E. = ?
Formula:
P.E. = Wh
P = P.E. / t
Solution:
P.E. = (65)(2)
P.E = 130 Joules
P = P.E. / t
P = 130 / 4
P = 32.5 Watts
