15. A 65 kg person is out riding their bike in a circle with a radius of 22.3 m. In order to stay on the road they need a centripetal forceof 186.5 N. A. What must be their acceleration? [2.87 m/sB. How fast must they be traveling? [8.0 m/s]C. What is their period? [17.5 s]D. How many laps will they make in 10 minutes? [34.25

Identify the forces that contribute to the centripetal force on the object in each of the following examples: a. a bicyclist moving around a flat, circular track b. a bicycle moving around a flat, circular track c. a racecar turning a corner on a steeply banked curve

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
