At what part of the trajectory does a projectile have minimum speed?
A projectile has minimum speed at the top of the trajectory.
What are the minimum points of reference needed to determine a trajectory (line)?
The answer depends on the sort of trajectory. If it isthe trajectory of a projectile, affected only by gravity then 3 points are enough. As soon as you add other forces: such a drag or continued propulsion, the number of points required increases.
How do you figure out the height and distance a confetti cannon will shoot?
By statistical analysis. It is very difficult to calculate these using mechanics. Calculations of the trajectory of a projectile assume that the mass of the projectile is such that air resistance has a negligible effect. This is not the case when the projectile is confetti - even if it is packed densely to start with.
How is maths used in weaponry?
locating objects; calculating the trajectory of a projectile; developing weapons uses engineering which uses lots of math
How do you determine velocity time and height using quadratics?
The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.
