| 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
5kg 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 2kg is in a rather large bowl and slides subject to friction
as depicted in the above animation.
