A toy car travels around a flat circular track, at a constant speed, one full revolution every 6 seconds. Show your work and include units in your answers. The radius of the track is 1.1 meters. The mass of the toy car is 0.12 kg. T = 6 s, r = 1.1 m, m = 0.12 kg a) How fast is the car traveling? (What is it’s tangential velocity?) aaa bonus) What is the car’s angular velocity? b) In which direction is the car accelerating? c) What is the car’s centripetal acceleration? ccc bonus) What is the car’s angular acceleration? d) What is the magnitude of the centripetal force acting on the car? e) What is the frequency of the car around the track?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
