Question1
Asteroids can be classified into two broad groups based on their composition and location: carbon-rich asteroids dominate an outer part of the asteroid belt, while metal-rich asteroids dominate the inner part of the belt. Study of the fragment we have discussed in this project reveals that it contains nearly equal amounts of metals and carbon. Can we terminate that original asteroid had a similar composition? Form a hypothesis about the origin of this asteroid based on the existing information.
Question2
A tow truck pulls a car 5.00 km along a horizontal roadway using a cable having a tension of 850 N.
(a) How much work does cable do on the car if it pulls horizontally? If it pulls at 35° above the horizontal?
(b) How much work does cable do on the tow truck in both cases of part (a)?
(c) How much work does gravity do on the car in part (a)?
