A 633-nm laser light is passed through a narrow slit and the diffraction pattern is observed on a screen 6.0 m away. The distance on the screen between the centers of the first minima on either side of the central bright fringe is 32 mm. How wide is the slit

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.

Refer to your lab guide and review the data in table b to complete each statement. the mass of g1 + g2 after the collision kg. the velocity of g1 + g2 after the collision m/s. the momentum of the combined gliders after the collision kg · m/s.
