Question

A speedboat moving at 30.5 m/s approaches a no-wake buoy marker 100 m ahead. The pilot slows the boat with a constant acceleration of -3.80 m/s^2 by reducing the throttle. (a) How long does it take the boat to reach the buoy (s)? (b) What is the velocity of the boat when it reaches the buoy? m/s

Step 1

Given: Initial velocity, \(u = 30.5 \, m/s\) Acceleration, \(a = -3.80 \, m/s^2\) Displacement, \(s = 100 \, m\) Plugging in the values: \(v = \sqrt{(30.5)^2 + 2(-3.80)(100)}\) \(v = \sqrt{930.25 - 760}\) \(v = \sqrt{170.25}\) \(v = 13.04 \, m/s\) Show more…
