A 65 kg baseball player gets the sign to steal second base. He runs full speed and reaches a top speed of 6 m/s before he decided to slide head first into second base. The distance between bases is ~27 meters (90ft) and the force of friction the runner experiences is 450 N once sliding. If the runner wants to reach second base touching it with just his hands, how far should he go for the slide after leaving first base? A. 0.43 m B. 24.4 M C. 2.6 m D. 26.6 m

(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.)
