Question

Hari drags a load of 60kg along a distance of 12m . What amount of work does he do ?
if answer is 7200J {what is the formula }(Full Explanation Please )

Answer 1

Explanation:

they used accelaration due to gravity = 10 m/s^2

and used it the potential energy formula

P.E. = mgh

here m = mass = 60kg

g = 10 m/s^2

height /distance (h) = 12m

multiply them all and you will get 7200 J ..

both energy and work have same unit i.e. joule(J)

coz the capacity to work is energy.. so they are same
