Peter designed a road with a curve of radius 30 m that is banked so that a 950 kg car traveling at 40.0 km/h can round it even if the road is so icy that the coefficient of static friction is approximately zero. neglect the effect of air drug and rolling friction. if the coefficient of static friction between and the road and the tires is .30 what is the safe range of speed?

Explanation:

When coefficient of friction is approximately zero then we have

here we know that

R = 30 m

now when friction coefficient is 0.30 then we have

now we have

it is easily magnetized.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
