A rock to the right with an initial horizontal velocity of 4m/s lands after 5 seconds. What horizontal distance has the rock traveled ?

What is the final velocity of the initial velocity of 25 and -50?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

What is a neurotransmitter involved in mood reward, addiction, and motor behaviors?
