  2. Trebuchet Projectile Physics - Height Formula

    www.physicsforums.com/threads/trebuchet-projectile-physics-height-formula.237503

    1) Work out the angle from the base of the trebuchet, to the point where the ball is released, by doing tan-1 (y/x). y is the height from the base of the trebuchet, to the top of the arm, where the projectile is released. x is the width of the base. 2) Use this formula; height = [ (tanθ) (X/t)]^2 + (sinθ) (2m) 2g.

    Height Momentum. In summary, on a frictionless track with a block of mass 8.00kg released from a height of 5.00m at point A and colliding with a block of mass 10.0kg at rest at point B, the two blocks stick together and the final velocity can be determined using the equation [1/2 (MVf^2)-1/2 (MVi^2) + (MGHf - MGHi).

    I / V gives the distance between the metacenter M and the center of buoyancy B. In other words, BM = I / V. The metacentric height of a vessel is usually taken as the distance between the center of gravity G and the metacenter and is referred to as the GM. A stable vessel will have a positive value of GM, i.e., G is always located below M.

    In summary: Simplifying:t = \sqrt {\frac {1.16} {9.81}} = \sqrt {0.118} = 0.344 seconds.In summary, the hang time of an athlete jumping 0.58 meters vertically can be calculated by using the formula t = sqrt (1.16/9.81), which equals 0.344 seconds. This formula is derived from the concept that total hang time is equal to twice the time it takes ...

    Derive a formula to calculate the height of the top of a hill on a roller coaster using triangulation. Final answer should be in terms of d, angle 1, and angle 2. There are two points on the ground. Angle 1 is the angle formed between the ground and a line that goes from the point closer to the hill to the top of the hill.

    4. How can momentum be used to find the height of an object? The formula for calculating momentum is p = m x v. If we know the momentum of an object at a certain height, we can rearrange the formula to solve for the height. This would look like: h = p / (m x v). This formula can be used to find the height of an object thrown into the air or the ...

  10. Kinematics: find maximum height - Physics Forums

    To calculate the maximum height in kinematics, you can use the equation h = u 2 sin 2 (θ)/2g, where h is the maximum height, u is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity. Alternatively, you can use the equation h = (v y ^2 - u y ^2)/2g, where v y is the final vertical velocity and u y is ...
