The surveyor laid the baseline at some distance x from the mountain. Since the triangle formed is isosceles, the perpendicular from the apex (x) bisects the side. So x = 500 tan 88. However, this is the distance to the mountain summit, not the ground distance from the base line to the...

A surveyor is trying to determine the height of a mountain. First, he msut determine how far away it is. He establishes a base line of 1km and measures the angle to the summit from both ends of the base line. The angle on the right side is 88degrees and the angle on the left end is 88degrees...

A triangle has an angle A=35 degrees and an angle B=40 degress and side a=3680 meters. What are the lengths of sides b&c?

Homework Statement A 1kg engine rotates at 1 rad/sec about a point on a 3meter wire. The engine produces an acceleration of 1 rad/sec^2 and is fird for 2 minutes. a) What is the ω at the end of 2 minutes? b) what's the tension in the wire at the end of 2 min.? c) how far will the engine...

anyone??:cry:

Homework Statement What is the formula that relates the period of a pendulum on a rotating coordinate system to the angular velocity of the coordinate system? (assume pendulum is in a gravitational field that produces an acceleration equal to the gravitational acceleration on Earth's surface)

pendulum! help! Homework Statement A pendulum 2 meters long with a mass of 1kg is mounted on a circular platform on the Earth's surface that's spinning at constant angular velocity. The pendulum is mounted on a pole that's perpendicular to the platform at a distance of 5 meters from the...

Homework Statement A pendulum 2 meters long with a mass of 1kg is mounted on a circular platform on the Earth's surface that's spinning at constant angular velocity of .12 rads/sec. The pendulum is mounted on a pole that's perpendicular to the platform at a distance of 5 meters from the center...

so would you say that the ship, for my homework's sake, is moving left of the x direction after all of this firing of shells has been made?

negatory, sir.

actually, I would like to answer my own question... Multiplying cos(10) and (770) gives one the velocity in the x direction, which is what I want. Multiplying three simply takes into account the 3 projectiles. You are as well a life saver, denverdoc and you too are deemed greatful to partake...

you do indeed have a very strong point when noting this new initial velocity has turned the momentum problem into a bit of an error. However, i am a bit perplexed as to whether the equation you presented above clearly depicts the shell's (or projectile's) velocity if one multiplies along with it...

If I had the power to bestow upon you a salmagundi of riches beyond belief, you would be the first person to share in this wealth. THANK YOU!

Homework Statement A 10kg objects rotates on a point on a wire 3 meters long at the rate of 120 rad/sec without breaking the wire. 1) What is the numeric value (and units) of the velocity vector and 2)what angle does it make with the tangent at any point? and 3) What's the minimum tensile...
