Acar drives straight down toward the bottom of a valley and up the other side on a road whose bottom has a radius of curvature of 115 m. at the very bottom, the normal force on the driver is twice his weight. at what speed was the car traveling?

33.58794 m/s

Explanation:

= Cenrtipetal force =

m = Mass of car

r = Radius of curvature = 115 m

g = Acceleration due to gravity = 9.81 m/s²

The normal force is given by

At the bottom N = 2N

The car was traveling at the speed of 33.58794 m/s

a and b sometimes have a positive value

the higher the current the higher the mag field around it the higher the influence on the compass
