Question 1 - What is the maximum speed with which a lZOO-kg car can round a turn of radius 90m on a flat road if the coefficient of friction between the road and tires is 0.65? Is this coefficient of static or kinetic friction? Is the result independent ofthe mass ofthe car? Given that the acceleration due to gravity at the surface Mars is 0.38 of what is on the Earth and that Mar's radius is 3400-km. Determine the mass of Mars. Given: Radius ofearth = RE = 6.38 x 106 m Universal gravitational constant, 6 = 6.67 x 10'11 N m2 / kgz
