A stationary 1.67-kg object is struck by a stick. The object experiences a horizontal force given by F = at - bí2, where t is the time in milliseconds from the instant the stick first contacts the object. If a = 1500 N/(ms) and b= 20 N/(ms)2, what is the speed of the object just after it comes away from the stick at t= 2.74 ms?
