    How to come up with Dovetail Trailer's Minimum Ground Clearance given the Wheelbase?

    Hello there is a Dovetail Trailer with dimensions and angles illustrated in my attached pdf file and my question is, how do I come up with the correct answer of 4.736141" of ground clearance before bottoming out? I sort of fabricated the answer through multiple iterations slightly rotating the...

    Time untill Ball hits ground

    Hi - I have a Ball thats located 'H' meters above the ground Every second, this happens: - Ball moves 'S' meters in the downwards direction - 'G' is added to 'S' I need to figure out how many seconds it takes for the Ball to hit the gound. ( Time is integer only ) ... I think this is related...

    velocity problem: when does a projectile hit the ground?

    The height (in meters) of a projectile shot vertically upward from a point 2 m above ground level with an initial velocity of 24.5 m/sec is h=2+24.5t-4.9t^2 after t seconds. When does it hit the ground? At what velocity? I know the answers are 5.08 sec and -25.3 m/sec, respectively. I...

    How many pounds + volume of ground beef would fit into an American football?

    Hi all, I have a bit of a strange question. I'm making an American football made entirely out of meat. (The "Meat Ball") I've already decided to use a bacon weave to wrap it, (for protection, plus to call it a pigskin) but I need to come up with an accurate amount of 1. Volume and 2. Weight so...

    Express the height of the crate over the ground in terms of distance to the person

    A 20m ropes passes over a pulley 4m above the ground and a crate on the ground is attached at one end. The other end of the rope is held at a level of 1m above the ground and is drawn away from the pulley. Express the height of the crate over the ground in terms of the distance the person is...

    Solving: Time for an object to hit the ground

    So my exam is in 2 days and I am having so much trouble. I am a new member, thanks for taking the time to view this question. If an object is thrown downward at 26 m/s from the top of a building, 102m high, the equation relating to displacement (meters) and time (seconds) is: s = 1/2 gt^2 +...

    find the velocity vector and speed of plane relative to the ground

    Alright, this is very confusing. Q. Suppose an airplane is pointing due west and flying with an airspeed of 500mph, and that there is a 200mph wind out of the south west. Find the velocity vector of the plane relative to the ground. What is the speed of the plane relative to the ground?

    Find the times when you're 65 feet off the ground.

    So, there's a Ferris wheel. I have to find out the times when you are 65 feet off the ground within the first four minutes, with t being the time in minutes, with this equation: h(t)=50-42sin(\frac{\pi}{2}t) I also had to solve it graphically, which was easy, so I know there are two points in...

    What is the V at the ground

    I have Gun A with Vo of 30m/s shot upward into the air and Gun B shot towards the ground at the same Vo. Now I know a for A is -9.8 and a for B is 9.8. As Vo is 30m/s when it hits the ground is it 0 m/s. That is what I am not sure of. But I did calc time on Gun A with t=V-Vo/a and get...

    Solving for theta of a projectile over uneven ground

    Hello- I put this question in this forum because I didn't really think it fell under "trigonometry", and this was the only category that seems to somewhat fit. I am modeling a projectile on a computer program, and need a formula to solve for the angle necessary for a projectile shot at a...

    first of all I wish to express my gratitude for the existence of the forum and especifically to those people that help us, the ones that have a math problem and have no idea how to solve it, like me. So thank you for your help in a world that has become too selfish for my taste. Thank you. My...

    Finding height from ferris wheel to ground.

    Hi, thank you for taking the time to look at my little problem. The figure shows a simplified model of the first Ferris wheel. The radius of the first Ferris wheel was 125 feet, and the distance from the ground to the bottom of the wheel was 14 feet. If (-) is the central angle formed as a...

    time for ball to hit the ground

    I've tried this problem 4 times now and i keep getting the wrong answer. I thought it would be a simple quadratic equation problem but I'm just not getting it. A baseball is “popped” straight up by a batter. The height of the ball above the ground is given by the function , where t is time...

    Finding the time it takes to hit the ground

    The question reads The ball is tossed up in the air from a tower 50m above the ground. If the ball has an inital velocity of 30m/s, how long will it take to hit the ground if a = -9.8m/s^2. Now ive got my velocity function v = -10t +30, my height function h = -5t^2 +30t + 50, how can I find...

    Force of ground when jumping

    When jumping straight down, you can be seriously injured if you land stiff-legged. One way to avoid injury is to bend your knees upon landing to reduce the force of the impact. A 75 kg man just before contact with the ground has a speed of 6.0 m/s. (a) In a stiff-legged landing he comes...
