Thanks for the help rock but i figured it out just before i saw your post.
F=ma
F=60x3
F=180N
=extra force added to weight
therefore the total value showed on the scale is
W= 180N + 600N (the mass converted to weight)
W= 780N
M= 78kg
Thanks again for the help
Homework Statement
the question given is:
What would the reading on a bathroom scale be if a 60kg pupil was accelerated upwards at a rate of 3m.s-2
Homework Equations
F=m(g-a)
F=ma
The Attempt at a Solution
F=m(g-a)
F=60kg(10m.s-2-3m.s-2)
F=600-180
F=420N which is...
