An engineer must design a curved exit ramp for a highway in such a way that a car, exiting at the posted speed limit of 15.64 m/s (35 mi/hr), does not depend on friction to round the curve without skidding. the radius of the curve is 182.0 m. at what angle with respect to the horizontal must the curve be banked (in degrees)?

Hey.. ♥️♥️ me in solving this question

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.
