Aprojectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. it is fired at an angle 33° with respect to the horizontal and with an initial speed of 49 m/s. air resistance is negligible in this situation.
a) what is the horizontal distance that the projectile has traveled when it is at its maximum height?
b) the same projectile was then fired in the same way toward a wall that is a horizontal distance 55.8 m from where the projectile was fired.
what was the height of the projectile when it hit the wall?
c) find the velocity of the projectile when it hit the wall.
you will enter your answer using the unit vector notation where the value in front of the i is the x component and the value in front of the j is the y component.
call up the positive y direction, and toward the wall the positive x direction.
d) what was the speed of the projectile when it hit the wall?

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
