A sled weighing 60N is pulled horizontally across snow so thatthe coefficient of kinetic friction between sled and snow is 0.100.A penguin weighing 70N rides on the sled. If the coefficient ofstatic friction is 0.700, find the maximum horizontal force thatcan be exerted on the sled before the penguin begins to slideoff.

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
