The figure below shows a force vs acceleration graph for a single object of mass m . Force and acceleration data have been plotted as individual points at several force strengths. A continuous line has been drawn through the points. Draw and label, directly on the figure, the force vs acceleration graphs for objects of mass (A) 2 m (B) 0.5 m 2m 0.5m
(N3T.3) A box sits at rest on an inclined plank. How do the magnitudes of the normal contact force and the gravitational force exerted on the box compare? (Hint: draw a picture!) (A) F N < F g (B) F N = F g (C) F N > F g (D) F N = 0 ! (E) We do not have enough information to answer.
