Engineering Mechanics - Dynamics Chapter 12 Solution: a v 2 ρ = a 180 ft s 2 = a' v 2 ' = a' 72 ft s 2 = Note that the time doesn t matter here because the speed is constant. * Problem 12-104 A boat is traveling along a circular path having radius . Determine the magnitude of the boat’s acceleration when the speed is v and the rate of increase in the speed is a t . Given: 20 m = v 5 m s = a t 2 m s 2 = Solution: a n v 2 = a n 1.25 m s 2 = aa t 2 a n 2 + = a 2.358 m s 2 = Problem 12-105 Starting from rest, a bicyclist travels around a horizontal circular path of radius at a speed v = b t 2 + c t
