Amodel rocket rises with constant acceleration to a height of 3.1 m, at which point its speed is 28.0 m/s. a. how much time does it take for the rocket to reach this height?
b. what was the magnitude of the rocket's acceleration?
c. find the height of the rocket 0.10 s after launch.
d. find the speed of the rocket 0.10 s after launch.

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
