Like filiplarsen has mentioned, you'll need more details for more accurate measurements...
but if you were to simplify the case,
by ignoring air resistance
you could calculate the speed of the plate just before it hit the head by the work-energy theorem.
it comes out to be approx 16...
My doubt is on the angular wave number 'k'
in case of a sinusodal wave on a string,
the angular wave number
k = (2*pi)/lambda
lambda being the wave length of the wave.
What does 'k' signify in physical terms ?
for e.g.
general wave number = 1/lambda
again, lambda being...
well...if you are shooting from level ground
then the maximum range(R) of the projectile will be
R= ( ^{}u^2 )/g
so your answer would be..approx 1020 feet...
actually for a projectile fired from level ground on solving the various equations of motion you'll get
Range = {...
a charged particle ( say 'q' ) moving with velocity 'V' in a region containing a magnetic field 'B' experiences a force 'F' given by:
[FONT="Arial Black"]F = q(VxB)
when
V = 0,
then force = 0
my doubt is,
is this velocity relative to the magnetic field ?
( i.e. when the velocity...
