Q. A 0.200-kg block along a horizontal track has a speed of 1.80m/s at once before colliding with a light spring of force constant 44.2 N/m located at the end of the track.
What is the spring's maximum compression if the track is frictionless?
In one design, a large spring with spring constant 2×10^4 N/m was placed behind the cannon. The other end of the spring braced against a post that was firmly anchored to ship's frame.
While the dried up seed pod of a scotch broom plant bursts open, it shoots out a seed with an initial velocity of 2.4 m/s at an angle of 60° above the horizontal.
An electron and a proton each have a thermal kinetic energy of 3×kBT/2. Compute the de Broglie wavelength of each particle at the temperature of 2050 K. (kb is Boltzmann's constant, 1.38×10-23 J/K).
what rate must air be moving through the open window in order to keep the system in equilibrium.
