A (n) 9.9 g bullet is fired into a (n) 138 g block of wood at rest on a horizontal surface and stays inside. After impact, the block slides 13 m before coming to rest. The acceleration of gravity is 9.8 m/s^2.

What is speed and what is velocity?

Through both refraction and diffraction, the atmosphere alters the apparent speed and, to a lesser extent, the direction of the signal. This causes an apparent delay in the signal's transit from the satellite to the receiver.
