Question

The load m = 1200 N is to be lifted to a height of 8 m. What is the work W (in J) that is needed to be done for this

Answer 1

Answer:

9600 J

Step-by-step explanation:

As,

W = F x S

W = 1200 x 8

W = 9600 J

Hope it helps.

Answer 2

Answer:

work done will be equal to potential energy which is equal to mgh

F= 1200N

F= ma

then 1200/10=m

m= 120kg

now putting in formula

mgh= 120*10*8

=9600J
