The He-Ne laser shines through a slit in the diffraction plate that is 50 cm from the screen. What fringe spacing would you expect for slits E and F if the stated slit spacing is correct? What difference must there be between the patters produced ..
A box full of books rests on a wooden floor. The normal force the floor exerts on the box is 236 N. (a) You push horizontally on the box with a force of 129 N, but it refuses to budge.
Calculate momenta before collision of the objects with masses m1=10g and m2=20g, moving with speeds v1=2m/s and v2=7m/s
An object initially at rest experiences an acceleration 1.5m/s^2 for 6.0s and then travels at the constant velocity for another 8.0s. What is the objects average velocity over the 14s interval?
For my project I constructed a trebuche. A trebuche is an ancient device used for launching projectiles. It acheives this by harnessing potential energy and allowing this potential energy to convert into kenetic energy. This potential energy is st..
