Aglass soda bottle is emptied of soda and filled to the very top with water. a cork is carefully fitted into the top of the bottle, leaving no air between the cork and the water. the top of the bottle has a diameter of d_top = 2.00 cm and the bottom of the bottle has a diameter of dbot = 6.50 cm. the glass breaks when it is exposed to p_max = 70.0 mpa of pressure.
a student hits the cork sharply with her fist and the bottom of the bottle breaks. the student's fist has a mass of m = 0.480 kg and moves downward at a speed of vi = 5.00 m/s. it collides elastically with the cork and rebounds with the same speed. the collision lasts for t = 1.20×10-4 s. in this problem, the positive direction is upward.

what is the force that the fist exerts on the top of the bottle?

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

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.
