F
, as shown in the figure. Which of the following statements are false? (a) The work done by
T
on sled
A
is half the work
F
does on
B
. (b) The work from friction on
B
is twice the work from friction on
A
. (c) The change in energy of the A+B system is zero. (d) The net impulse exerted on
A
is less than on
B
. (e) The net impulses exerted on both
A
and
B
are zero. (f) Both
A
and
B
experience positive net external work. (g) Both
A
and
B
experience negative net external work. (h) Both A and B experience zero net external work. 2) The figure shows several plots, one of which labeled as representing the position of a mass on a frictionless surface, connected to a horizontal spring that is oscillating back and forth. The other two plots are num. bered I and II. Which of the following statements are true regarding these plots and this situation? (a) Plot I could represent the mass's velocity as a function of time. (b) Plot I could represent the mass's acceleration as a function of time. (c) Plot II could represent the mass's acceleration as a function of time. (d) The mass has the greatest amount of potential energy at points
A,C
, and
E
. (e) The mass has the greatest amount of kinetic energy at points
A,C
, and
E
. (f) The potential energy of the mass is maximum when its magnitude of acceleration is greatest. (g) The kinetic energy of the mass is greatest when its position is zero. The multiple select questions end now.
