1.A 345-kg sailboat has an acceleration of 0.801 m/s2 at an angle of 50.1 ° north of east. Find (a) the magnitude and (b) the direction of the net force that acts on the sailboat. 2.Boat A negotiates a curve whose radius is 504 m. Boat B negotiates a curve whose radius is 180 m. Each boat experiences the same centripetal acceleration. What is the ratio of the speed of boat A to that of boat B?

Step 1
To find the magnitude of the net force, we can use Newton's second law, which states that force equals mass times acceleration: F = ma. Plugging in the given values, we get: F = (345 kg)(0.801 m/s^2) = 276.345 N So the magnitude of the net force is 276.345 N. Show more…

A speedboat with a length of 10.2m and a mass of 239 kg is negotiating a circular turn (radius 30 m) around a buoy. During the turn, the engine causes a net tangential force of magnitude 541 N to be applied to the boat. The initial speed of the boat going into the turn is 4 m/sec. What is the tangential acceleration of the boat, 2 sec into the turn? 'sec2 Submit What is the tangential velocity of the boat, 2 sec into the turn? VT m/sec Submit What is the centripetal acceleration, 2 sec into the turn? acen m/sec2 Submit What is the total acceleration, 2 sec into the turn? m/sec2 Submit

An aircraft undergoes two displacements. If the first displacement is directed at an angle of 214° with the positive x-axis and has a magnitude of 36.0 miles, and if the resultant displacement is directed at an angle of 78.0° with the positive x-axis and has a magnitude of 40.0 miles, what are the magnitude and direction of the second displacement? (Both angles are measured counterclockwise from the +x-axis.) a. Magnitude (in mi) b. Direction (in ° counterclockwise from the +x-axis) 2. Corrected_text: A speedboat moving at 33.0 m/s approaches a no-wake buoy marker 100 m ahead. The pilot slows the boat with a constant acceleration of -3.85 m/s^2 by reducing the throttle. a. How long does it take the boat to reach the buoy? b. What is the velocity of the boat when it reaches the buoy?
