Read the question carefully and give me right solution according to the question.  A 1,200 kg car drives at a constant speed around a circular track. The coefficient of kinetic friction between the tires and the surface is 0.30, the height (h) of the car is 0.50 m, and the tread (G) is 1.40 m. If the angular velocity of car is 0.20 rad per second, compute the radius of the track

A physics experiment is set up using two pulleys, a string, and a weight as shown below. The larger pulley has a radius of 14 centimeters, and the smaller pulley has a radius of 8 centimeters. The distance between the centers of the pulleys is 56 centimeters. The string is pulled tightly across both pulleys so that F is a common tangent of the pulleys. Find the length of string from A to B to the nearest tenth of a centimeter. A weight O 56.0 cm O 22.0 cm O 55.7 cm O 58.5 cm
