including your doctors recommendations and your height and weight 3. Now to calculate the increase in energy output, just divide modified toy KE by original control toy KE then convert to percentage: I n c r e a s e ( K E 2 K E 1 1) × 100. The calculation here goes something like this: (50mg/1) X (1ml/15mg) 50ml/15 (Mg. Al the distance are measured from pole in either direction's. And the next step is to input this value into the kinetic energy formula as follows: K E m v 2 2. And for height apply magnification formula (-v/u = h'/h) where h' is height of image and h is height object. Two find the distance x apply the following formula (1/u 1/v = 1/f) where u is the distance of the object from p v is the distance of the image from the p and f is the focal length. The point of intersection of the two ray's will give you the distance of the object from the pole p. The Projectile Motion Calculator is provided in support of our Physics Tutorials on Dynamics which explore Motion. If it is a elongated object of height h from the optical axis then you will have to take two rays ray 1 and 2 as given in the fig. But it is applicable only for point object. If the travelling ray is striking at the pole of the mirror then the the reflected ray will be of same length and height from the optical axis and you will get the height of the object.

Now if we want to know the free fall distance, using the formula s 0.5 g t2 0.5 9.806.50 m (check with the free fall calculator ). Can anyone tell me if this would work for my problem?Ĭalculation is easy you can apply the mirror formula and magnification formula which will give yo the position of the new image and it's magnification through which you can find the angle of the reflected ray. Physics and science calculator solving for weight or force given mass and gravity. Now if we want to know the final free fall velocity, using the formula V V0 g t 0 9.80665 15 147.10 m/s (check with the free fall calculator). We choose a kinematic equation based on what parameters. After rearranging the terms in these three equations to solve for acceleration, they are given as: 1.) a (v v0) t. humidity but not with air pressure (atmospheric pressure) and height. There are four kinematic equations, but only three of them can be used to solve for acceleration. I tried to use the matrix method to solve this problem, but I don't even know if this would work or not. Speed of sound temperature air no barometric pressure calculation temperature. Example: at a length of 10 and a height of 5 meters, the angle of slope. How can I find the height and angle of the ray 1m away from the point reflected? I've looked at three optics books, and I still can't find an easy explanation for calculating this. Collection of important formulas of math and physics, with calculators: rolling. The ray travels a distance of 2cm and comes in contact with a concave mirror of R = 1. I know the mirror is concave and the radius of curvature, and I know the parameters listed above, but how should I write an equation to find the height and angle of a reflected ray?ĮDIT: For example, I have a ray 5mm from the optical axis, and it propagates at 0.3 mrad to that axis. A strong bow and a light arrow could make the shot, but targets would hardly be visible at that. Determining if Wildling arrows could reach the top of The Wall in George R.R.Martins 'Game of Thrones'. If I have a ray of light at a certain height from the optical axis, propagating at an angle, and the distance it travels before it comes in comes in contact with a mirror, can I find the angle and height of the ray after it reflects? Calculates the flight duration, maximum height and travel distance of the projection from the initial velocity and angle. That's it! We've derived the trajectory formula.I barely know anything about optics, so I could use some help about how to go about solving this problem. y = h V y t − g t 2 / 2 y = h V_y t - g t^2/2 y = h V y t − g t 2 /2Īs the launch velocity ( V 0 V_\text y = h x tan α − 2 V 0 2 c o s 2 α g x 2 . Where does the vertical distance formula come from?įirst, let's remember the equations of motion for the horizontal ( x x x) and vertical ( y y y) positions:
