How Much Work Is Done On The Package By Friction As It Slides Down The Circular Arc From A To B?

Q: How much work is done on the package by friction as it slides down the circular arc from A to B? A: PE at top = mgh = 0.200kg * 9.8m/s² * 1.60m = 3.14 J KE at bottom = ½mv² = ½ * 0.200kg * (4.10m/s)² = 1.68 J

How is a small package released from a truck-loading station?

In a truck-loading station at a post office, a small 0.200 kg package is released from rest at point A on a track that is one-quarter of a circle with radius 1.60 m (the figure ). The size of the package is much less than 1.60 m, so the package can be treated as a particle.

What is the speed of the package on the track?

The size of the package is much less than 1.60 m, so the package can be treated as a particle. It slides down the track and reaches point B with a speed of 4.10 m/s. From point B, it slides on a level surface a distance of 3.00 m to point C, where it comes to rest.

What is the speed of the block sliding down the ramp?

A block slides down a frictionless inclined ramp. If the ramp angle is 17.0 degrees and its length is 30.0 m, find the speed of the block as it reaches the bottom of the ramp, assuming it started sliding from rest at the top. 13.1 m/s

How far does a block move when compressed?

A block with mass 0.50 kg is forced against a horizontal spring of negligible mass, compressing the spring a distance of 0.20 m (Figure 1). When released, the block moves on a horizontal tabletop for 1.00 m before coming to rest.
