A cart is moving along a track to the right with constant speed v. Evidently the net force
acting upon the cart is.
A. rightward.
B. zero.
C. leftward. - Answers -
A cart is connected to a hanging mass by a rope draped over a pulley. There is no
friction (drag) between the cart and the track, nor the rope and the pulley. The cart and
hanging mass have equal mass. Once released from rest, the hanging mass will fall
with an acceleration of magnitude
A. zero.
B. Less than 0.5g but greater than zero.
C. 0.5g.
D. Greater than 0.5g but less than g.
.E. g. - Answers -
A cart is connected to a hanging mass by a rope draped over a pulley. There is no
friction (drag) between the cart and the track, nor the rope and the pulley. The cart and
hanging mass have equal mass. Once released with the initial velocity shown, the
hanging mass will fall with an acceleration of magnitude
A. zero.
B. Less than 0.5g but greater than zero.
C. 0.5g.
D. Greater than 0.5g but less than g.
E. g. - Answers -
Cart C is connected to hanging masses A and B by means of ropes and pulleys as
shown. A and B are equal mass bodies. After being given the initial velocity shown, cart
C will
A. speed up.
B. stay at the same speed.
C. slow down and stop.
D. slow down, stop, and reverse its direction - Answers -B. stay at the same speed.
, Cart C is connected to hanging masses A and B by means of ropes and pulleys as
shown. A is heavier than B. After being released into motion from rest, the tension in A's
rope will
A. Remain greater than that in B's rope.
B. Become equal to that in B's rope.
C. Become less than that in B's rope. - Answers -A. Remain greater than that in B's
rope.
A skydiver is falling with the parachute open. The rate of descent is a steady 8 m/s. We
can conclude that the net force acting upon the skydiver is
A. upward.
B. zero.
C. downward. - Answers -B. zero.
Car A and truck B are moving with the same speed down a long straight level highway
side by side. They are each outfitted with new Goodyear tires. They brake
simultaneously without the benefit of antilock brakes such that all of their wheels lock.
Each skids to a halt. B weighs 9 times more than A. The magnitude of B's acceleration
is
A. 9 times greater than A's.
B. 3 times greater than A's.
C. Equal to A's.
D. 1/3 times that of A.
E. 1/9 that of A. - Answers -C. Equal to A's.
Block A and block B are both made of white pine wood and placed on identical ramps.
The angle of the ramps is such that Block A is just able to remain at rest. Block B is
twice as heavy as block A. Block B will
A. Slip down the ramp.
B. Also be just able to remain at rest.
C. Remain at rest with tilt to spare (could remain at rest for even a steeper ramp). -
Answers -B. Also be just able to remain at rest.
Block A and block B are both made of white pine wood and set to slide on identical
ramps. Block A is sliding down the ramp. Block B is sliding up the ramp. Which
experiences the greater magnitude of acceleration?
A. Block A.
B. Block B.
C. Both experience the same magnitude of acceleration.
D. Cannot determine without knowing the initial speed of launch. - Answers -B. Block B.
