We are building a road, and at one place we need to make a turn with a radius of 25m. The coefficient of static friction between the rubber and the material we are using is 0.6.
(a) Assuming that the road is flat through the turn, what is the maximum speed a car could have and safely navigate the turn without sliding off the road?
(b) Instead of keeping the road flat, let's bank the turn a little bit, giving the road an angle of 20° above the horizontal. With the banked turn, what is the maximum speed a car could have and still make it around the turn without sliding?

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?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
