A car can go around a curve of radius 43m at a speed of 12 m/s without skidding . What is the angle of banking?

At takeoff a commercial jet has a 60.0 m/s speed. Its tires have a diameter of 0.700 m. (a) At how many rpm are the tires rotating?  rpm (b) What is the centripetal acceleration at the edge of the tire?  m/s2 (c) With what force must a determined 10−15 kg bacterium cling to the rim?  N (d) Take the ratio of this force to the bacterium's weight.  (force from part (c)/bacterium's weight)

A car negotiates an unbanked 81.7 m radius curve at 17.4 m/s.   What would the minimum coefficient of friction be needed to negotiate the curve?

The peripheral speed of the tooth of a 10-in.-diameter circular saw blade is 150 ft/s when the power to the saw is turned off. The speed of the tooth decreases at a constant rate, and the blade comes to rest in 9 s. Determine the time at which the total (or resultant) acceleration of the tooth is 130 ft/s?.
