Question

help me plz...........................

Answer 1

By definition we have that the work done is given by:

W = F * d

where,

F -- force in the direction of distance and displacement

d--displaced distance

substituting the values I

W = (25) * (4) W ---100NM

Then the power is given by

P =w/t

where t is the time

substituting value we have,,

p = 100/5 =20

WORK DONE BY THE BOX IS 100NM AND THE POWER IS 20NM/S
