A boat is traveling along a circular path having a radius of 20 m. determine the magnitude of the boat's acceleration if at a given instant the boat's speed is v = 5 m/s and the rate of increase in speed is v = 2 m/s2.

acceleration = v²/r
= 5²/20
= 5/4 m/s²
(a)net = [2² + (5/4)²]½
= (4 + 25/16)½
= (89/16)½
= √89/4 m/s²
= 5²/20
= 5/4 m/s²
(a)net = [2² + (5/4)²]½
= (4 + 25/16)½
= (89/16)½
= √89/4 m/s²
