The drawing shows a version of the loop-the-loop trick for a small car. If the car is given an initial speed of 5.0 m/s, what is the largest value that the radius r can have if the car is to remain in contact with the circular track at all times?

**Physics**

A car is traveling around a horizontal circular track with radius r = 190.0 m at a constant speed v = 22.0 m/s as shown. The angle èA = 15.0° above the x axis, and the angle èB = 63.0° below the x axis. 1) What is the magnitude of the car’s acceleration? 2) What is the x ...

**Physics-circular force**

What is the maximum speed with which a 1140 kg car can round a turn of radius 65 m on a flat road if the coefficient of friction between tires and road is 0.80?
