Math Problem Statement
Suppose the position of an object moving horizontally after t seconds is given by the following function sequalsf(t), where s is measured in feet, with sgreater than0 corresponding to positions right of the origin. a. Graph the position function. b. Find and graph the velocity function. When is the object stationary, moving to the right, and moving to the left? c. Determine the velocity and acceleration of the object at tequals1. d. Determine the acceleration of the object when its velocity is zero. e. On what intervals is the speed increasing? f(t)equalst cubed minus 12 t squared plus 45 t; 0less than or equalstless than or equals7
