1. The position of a particle as a function of time is given as: Position(t) = 4 b t3 – 3 ct2 + d a. What are the units of the constants b,c and d? b. What is the position at time t= 0,1,2,5 s? c. What is the instantaneous velocity at time t= 0,1,2,5 s. d. What is the average velocity between 0-1 s; 0-2 s; 0-5 s? e. What’s the difference between average and instantaneous velocity? f. What’s the instantaneous acceleration at t= 0, 1,2,5 s? g. Can the equations of constant linear acceleration be used in this situation? Why or why not?
