A race-car starts at the 3 o’clock position and drives counterclockwise on a circular track with a radius 4 miles. a/ What distance (in miles) has the race-car traveled if the angle swept out by the race-car is: (i). 90◦ (degree)? (ii). 5 radians? b/ What is the angle measure (in radians) swept out if the race-car has traveled 4 miles counterclockwise? c/ What does it mean about the path of the car for the angle measure to be greater than 4π radians? Explain.

A dirt bike is traveling at a constant speed v when it happens upon a circular hill of radius r = 410 m. The driver and dirt bike together have mass m = 136 kg. a.) What speed in m/s does the dirt bike have if the driver feels weightlessness (i.e., has an apparent weight of zero) at the top of the hill? b.) If the driver is traveling at the speed above and happens upon a hill with a radiues 2r, what is the apparent weight of both the driver and the dirt bike in Newtons at the top of the hill?

An object moving in a circle with a radius of 0.5 meters accelerates tangentially at 5 meters per second squared. At the instant, the object’s net acceleration is 9 meters per second squared, determine its speed.
