A boat travels east at 5.0 m/s. A sudden gust of wind gives the boat an acceleration of (.80m/s^2, 40 degress north of east). What is the boat's speed and direction 6.0 s later when the gust subsides.

2 man, mass m1 and m2 stands on a boat mass M at L distance apart on static water. they slowly swop their places. find the distance the boat move due to this. ------------------------------------------------------------ i know that the centre of mass remains unchange, and at start...

Let me know if the following statement is wrong : If a boat is going to cross a river directly ( i.e perpendicularly ) the x, horizontal, component of the boat velocity must be cancelled, that's be equal, by the water stream vector. I followed this idea in a problem but my answer is not...

what is the formula for calculating water displacement. I used to know it. it was something simple like length times width times .85 I think. Can anyone help me calculate the total displacement for a barge 295 feet long 52 feet wide with a designed dwaterline depth of 9 feet...

okay, here's the problem as stated: A rectangular boat is 2m long and 0.8m wide and 0.2m high and weights 75kg. If the boat is in fresh water, find (a) the amount that it will sink into the water when Squink (98kg) jumps in, and (b) the number of 2kg fish he can catch before the boat sinks...

A King wants to pick his heir from among his 2 sons. They are to row their boats across the royal lake to the boathouse on the other side. The prince whose boat enters the boathouse first loses. Obviously, this puts the princes into a quandary, for they would gain by delaying for as long as...

Hi, I have a physics test on Monday and would like some help with these problems. Kinematics problems: 1. A boat starting from rest on a lake accelerates in a straight line at a constant rate of 2.0 m/s^2 for 6.0 s. How far does the boat travel during this time? 2. A bullet traveling...

The mass of a boat is M=80kg, the mass of a boy is m=36kg. The boy moves from the stern to the bows of the boat. What distance does the boat move, if its length is 2.8m? At such low speeds the water resistance may be neglected. Hint: Center of mass remains at rest. Please help becuase I am...

I'm not a Christian, but my opinion is that the focal point of the story (or myth) of Jesus was almost entirely absent in this film. I thought "the Passion..." failed to even marginally address the depth of spiritual suffering related in the story of Christ. While it was realistic in that it...

I'm really fired up about physics now. But I can't puzzle out the following: Q. When you float in fresh water, the buoyant force that acts on you is equal to your weight. When you float higher in the high-density water of Salt Lake, the B.F. that acts on you is actually: 1) greater than your...

I really need help solving question #2 from the following webpage: http://www.math.psu.edu/anand/M141/applied2/ . I've attempted to solve this, but looking at my answers, I'm not overly confident. In part a, I'm suppose to prove that tractrix somehow, and in part b, I believe I am to just...

I am stuck on this problem... A rowboat measures 4ft wide by 10ft long. How much (in inches) will the boat sink into the water when two 200 lbs me get into the boat? A: I am having a hard time getting the volume of the boat…does anyone have a suggestion? This was my plan: W boat=...

A question (and no, it's not for uni work). A boat sits in the water. Attached to the front of the boat is a bucket (or some other vessel), submerged. The bucket is sort 0of a black hole for water. Anything going into the bucket vanishes, to another world, the Pentagon, Michael Jackson's...

can u please tell me what i did wrong? A 70 Kg person stands at the back of a 200 Kg boat of length 4 m that floats on stationary water. he begins to walk toward the front of the boat. When he gets to the front how far back will the boat have moved? (neglect the resistence of water) The...

I've added a picture that's part of the problem. A sailboat race course consists of four legs defined by the displacement vectors A, B, C and D shown above. The values of the angles are È1 = 420, È2 = 410, and È3 = 270. The magnitudes of the first three vectors are A = 3.7 km, B = 5.3 km...
