Show work clearly, thanks.

A regulation NCAA basketball weighs 22 ounces (624 grams). Carsen Edwards shoots the ball with a velocity of 2.25 m/s. What are the values for: a. The momentum of the basketball (in kg m/s units) b. The wavelength of the basketball (in nm units) (remember the de Broglie relation, eqn 1.11 in the text) How do the above values for (a) and (b) compare to the momentum and wavelength of a He atom and an electron moving at 2.25 m/s? How do these wavelengths compare to the wavelength of a visible light photon? (remember, visible light spans wavelengths of 400 nm to ~800 nm) c.

    Please work out 3 clearly and with units. Thanks! 1. A 10-g bullet travels vertically upwards at 1000 m/s, then strikes and passes through a 2.0-kg block initially at rest. The bullet emerges from the block with a speed of 400 m/s because it transfers momentum to the block. (a) How much momentum did the block gain? (b) How fast is the block now moving, and what is its kinetic energy? (c) Using energy considerations only, to what maximum height...
