| 8.3.ap 1: A
bowling ball is lifted from rest onto a shelf by an external agent. |
8.3.ap 2:
A 12-kg box slides down a rough ramp at constant speed as shown in the
animation. Note that both gravity and friction do work on the box.
|
| 8.3.ap 3: A
ball on an air track is attached to a compressed spring as
shown in the animation. |
8.3.ap 4:
A 0.5-kg cart on an air track receives a push as shown in the animation. The
spring is initially unstretched with a spring constant of k=100N/m.
|
| 8.3.ap 5: A
12-kg box slides down a 30° frictionless ramp at constant speed as
shown in the animation. Note that both gravity and the hand do work on
the box. |
8.3.ap 6:
A pendulum of unknown mass is suspended from a platform and swings as
shown in the animation.
|
| 8.3.ap 7: A
5-kg block is lifted from rest by an external agent, then returned to its
original position as shown in Animation 1. An identical block is pushed
along the surface which has a coefficient of kinetic friction
of 0.2. As with the first block, it is returned to its
original position in Animation 2. |
8.3.ap 8:
A pendulum of unknown mass is suspended from a platform and swings as
shown in the animation (assume negligible loss of energy due to air
resistance; position is shown in meters and time is in seconds).
|
| 8.3.ap 9:
A 2-kg pendulum bob swings suspended from a platform as shown in the
animation above. |
8.3.ap 10:
A mass of 2 kg is in a rather large bowl and slides subject to friction
as depicted in the above animation.
