Q. An 11.0 g bullet is fired horizontally into a 108-g wooden block that is at first at rest on a frictionless horizontal surface and connected to a spring of constant 151 N/m. The bullet becomes embedded in the block. If the bullet-block system compresses the spring by a highest of 90cm, what was the speed of the bullet at impact with the block?
A 21 g bullet travelling at 255 m/s is fired into a 0.452 kg wooden block anchored to a 100 N/m spring. How far is spring compressed to the nearest thousandth of a meter.

Assume, instead, that the observer had been moving away from Earth with a speed of 0.80c. How much time would observer have measured for the car to be filled in this case.
Determine the maximum horizontal force that can be applied to the block before it slips.
A broad beam of light of wavelength 485nm is incident at 90° on a thin, wedge-shaped film with index of refraction 1.50. An observer intercepting the light transmitted by the film sees 17 bright and 16 dark fringes along the length of the film. By..
