Question

A man has weight 60 kg with 25kg load and climbed up at height 10 m on a stair . Calculate the potential energy. (G_10m/s2) P=mgh

Answer 1

Answer:

8500 joule

Explanation:

mass = 60 + 25 kg = 85kg

height = 10 m

g = 10m/s

so by mgh ;

85*10*10 = 8500j

Answer 2

Answer:

8500 JOULES

Explanation:

Mass of man = 60kg

Mass of the man while he was climbing = 60+25= 85 kg

Height of the stair case =10m

potential energy= mgh

                             MASS *ACC DUE TO GRAVITY*HEIGHT

                           =  85*10*10  

                           = 8500 JOULES
