If a rock is thrown upward on the planet mars with a velocity of 18 m/s, its height (in meters) after t seconds is given by h = 18t − 1.86t2. (a) find the velocity of the rock after one second. 14.28 correct: your answer is correct. m/s (b) find the velocity of the rock when t = a. correct: your answer is correct. m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = incorrect: your answer is incorrect. s (d) with what velocity will the rock hit the surface? m/s

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm

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?
