Interactive LearningWare 8.1 reviews the approach that is necessary for solving problems such as this one. A motorcyclist is traveling along a road and accelerates for 4.36 s to pass another cyclist. The angular acceleration of each wheel is 6.10 rad/s2, and, just after passing, the angular velocity of each is 75.2 rad/s, where the plus signs indicate counterclockwise directions. What is the angular displacement of each wheel during this time?

Adding more pulleys to a system of pulleys needed to lift an object. a. increases the force b. decreases the force c. increases the amount of work d. decreases the amount of work

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

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.
