Projectile motion i dont understand anything about projectile motion

Question edited for clarity, 'make model (what it is)'.
Question moved from Video Consoles to make model category.

I am having difficulty finding a manual, but as I understand it there is a switch for you can switch off chimes and movement at night when you go to bed.

How to Solve Time in Flight for Projectile Problem

Check your case; if you are reloading the issue will be that the cases have stretched ( standard outcome for all reloaders) and the lan is too long to allow the case and bullet to fit correctly.

As part of any rel;oading process length of case and condition of teh lan MUST BE CHECKED.

Or you are also NOT setting the projectile in to the case far enough

OR over loading with propellent and the projectile can not be seated correctly...

Could be a dozen other reasons, but would need the see and hold and test.. ..

This the problem of a projectile motion.
Assume the positive direction of the vertical axis is upward.
Let y_0 be the initial height, which we set=0.
Let v_0 be the initial velocity, a the acceleration, t the time, y the position at instant t, v the vertical velocity.
a=-g
v=v_0-gt
y=v_0*t-(1/2)*(g*t^2)
At what time is the highest point reached?
At the culmination point (highest point) the speed passes through the value 0. This happens at the time t_c given by
v_0-g*t_c=0 or t_c=v_0/g
Substitute this value in the equation for the position
y_c=v_0*t_c-(1/2)g*(t_c)^2
this gives y_c=(1/2*g)*(v_0)^2
As you can see the mass does not appear anywhere in this problem. Both masses will reach the same height.

1. Locate the sensor on the motion detector. The most common problem with a motion detector is a sensor that is obstructed or dirty. Remove any dirt, grime or anything else that may be blocking the view of the sensor. If you need to actually touch the sensor itself to clean it, use a soft cloth or cotton swabs.
   
2. Determine if the motion detector has electricity running through it properly. Connect an electrical meter to the wires from the sensor itself. If electricity is indeed running to the sensor, you likely have a broken senor. If there is no electricity making it to the sensor, your motion detector has an electrical short. In the case of an electrical short, you will need the help of a professional electrician to fix it.
3. Visit a hardware or supply store to buy a replacement sensor
   

Thanks for understanding.

You need to know the mass and velocity of the projectile

You have to obtain the correct projectile mould for the calibre of your weapon, and a small block of lead form your gunsstore. Heat the lead with a gas burner until molten and pour into the mould. Allow to cool, open the mould and clean up the projectile with fine file to remove casting edges. Now you can use it in you re-loader.

You don't. If you angle the laser, the path of the beam will intersect the path of the projectile fired from the rifle at one point (probably, unless you're shooting at a slightly upward angle and the laser is pointed straight, then the projectile will cross the path of the laser once as it rises, then again as it comes back down.). You've got basically two options. Either you zero the site at a certain distance, say 25 yards. Then you realize that the dot made by the laser is where your projectile is going to hit at 25 yards and the more you change that distance from your target the further off that point of impact will be. The other option is to mount it in such a way as to have the path of the laser beam parallel with the path of the projectile as it exits the barrel. Then just account for the fact the the point of impact will be that distance below the dot. Well, to a point anyway. After a while the bullet will be affected by gravity more and start to drop, but that's probably going to happen around the same time the dot from the laser loses focus.

surely the ball was having a ball with the table.. a 69 position could help taking the average time for it to come. and **** off on the floor with a velocity determined by the medium viscosity which ends upto a final value discovered by Indians --------- '0'
