3.(25 pts) Three boats are moving on a lake. The first boat (m 2570 kg) is moving at 12.5 m/s at 35.00 south of west. The second boat (m- 1560 kg) is moving at 9.65 m/s at 12.30 west of north. The third boat has a mass of 3350 kg. The boats collide, stick together, and move with a velocity of 4.55 m/s due west. Find the magnitude and direction (from the north) of the velocity of third boat.

A golfer, putting on a green, requires three strokes to "hole the ball." During the first putt, the ball rolls 3.1 m due east. For the second putt, the ball travels 3.5 m at an angle of 33.0 ° north of east. The third putt is 0.32 m due north. What displacement ((a) magnitude and (b) direction relative to due east) would have been needed to “hole the ball” on the very first putt?

1.A person is following a set of directions. He has to walk 2km2km east and then 1km1km north. He takes a wrong turn and walks south instead of north for the second leg of the trip. The magnitude of his total displacement will be the same as it would have been had he followed directions correctly. - TRUE OR FALSE 2. A person attempts to cross a river in a straight line by navigating a boat at 15m/s15m/s. If the...

It takes a golfer a total of three strokes to put the ball in the hole. The displacements of the three strokes are as follows: d1 = 4.20 m the north, d2 = 1.80 m northeast, and d3 = 1.10 m at θ = 30.0° west of south, If the golfer had made the hole in a single shot, what would be the displacement of the ball? (Assume the positive y- and x-axes are in the north and east directions,...

Mariana finds a cave to explore. Starting at the cave entrance, Mariana first follows a passage 75.0 m north, then turns and moves 250 m east, then goes 114 m at an angle 30.0° north of east, and finally moves 156 m south. Find the resultant displacement from the cave entrance. Shown is a sketch of the situation not drawn to scale. (Give the magnitude of the displacement in m and the direction in degrees south of east.)
