In a video game, a henchman is programmed to move around the screen to (theta) = 9.00t - 0.750t3, where (theta) is the angle in radians and t is the time in seconds.

a) At what time after starting is the henchman instantaneously at rest?

b) Where does this occure (give the theta)?

c) What is the angular acceleration when this occurs?

d) In which direction does the henchman move in the next instant after coming to rest?

n the game Force Master you move the character forward or backward across the screen by controlling their acceleration. By holding the motion key down, you can cause the acceleration to increase at a rate of 12 px/s3 ("px" stands for "pixels," a unit of distance for computer screens.) How far does the character get if you hold the key down for 5 seconds, assuming that they start at rest? [HINT: The acceleration can be described by the function a(t)=jt,...

A solid uniform disk of mass M = 9.6 kg and radius R = 21 cm rests with its flat surface on a frictionless table (i.e., the axis of the cylinder is perpendicular to the table.) The diagram shows a top view. A string is wrapped around the rim of the disk and a constant force of F = 10.8 N is applied to the string. The string does not slip on the rim. 1) What is the acceleration of...
