Question1
later than the Sun exhausts its nuclear fuel, its ultimate fate will be to collapse to a white dwarf state. In this state, it would have approximately the similar mass as it has now, but its radius would be identical to the radius of the Earth. Analyse
(a) Average density of the white dwarf,
(b) Surface free-fall acceleration, and
(c) Gravitational potential energy associated with a 1.00-kg object at the surface of the white dwarf.
Question2
A uniform horizontal bar of length L = 5 m and weight 210 N is pinned to a vertical wall and supported by a thin wire that makes an angle of theta = 15o with the horizontal. A mass M, with a weight of 339 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 565 N. What is the greatest possible distance from the wall at that mass M can be placed before the wire breaks?
What is coefficient of kinetic friction
A dockworker applies a constant horizontal force of 84.0\({\rm N}\) to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 12.5\({\rm m}\) in a time 4.80\({\rm s}\)
