You are designing a lathe motor, part of which consists of a uniform cylinder whose mass is 105 kg and whose radius is 0.60 m that is mounted so that it turns without friction on its axis, which is fixed. the cylinder is driven by a belt that wraps around its perimeter and exerts a constant torque. at t = 0, the cylinder's angular velocity is zero. at t = 25 s, its angular speed is 550 rev/min. (a) what is the magnitude of the cylinder's angular momentum at t = 25 s? kgm2/s (b) at what rate is the angular momentum kgm2/s2 (c) what is the magnitude of the torque acting on the cylinder? nm (d) what is the magnitude of the frictional force acting on the rim of the n

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
