The speedboat travels at a constant speed of 20 m/s while making a turn on a circular curve from A to B. If it takes 45 s to make the turn, determine the magnitude of the boat\'s acceleration during the turn.

a = ?

Solution

Let r be the radius of the circle

Distance = time*velocity

Here, Distance = Half Circumference = r

Therefore

r = 45*20

r = 286.47 m

Acceleration = v^2/r

= 20^2/286.47

1.39 m/sec^2
