A turntable must spin at 33.3 rev/min (3.49 rad/s) to play an old-fashioned vinyl record. How much torque must the motor deliver if the turntable is to reach its final angular speed in 2.30 revolutions, starting from rest? The turntable is a uniform disk of diameter 30.5 cm and mass 0.250 kg. N-m
What is the torque by the trash can about the center of the seesaw, in N-m? Use g = 10 m/s². Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 8 17 6 5 4 3 2 2 3 10 kg 4 5 6 7 8
A 7.62 kg particle with velocity = (9.74 m/s )î - (2.04 m/s ) Ĵ is at x = 3.16 m, y = 9.00 m. It is pulled by a 6.30 N force in the negative x direction. About the origin, what are (a) the particle's angular momentum, (b) the torque acting on the particle, and (c) the rate at which the angular momentum is changing?

5. ssm The drawing shows a jet engine suspended beneath the wing of an airplane. The weight W of the engine is 10 200 N and acts as shown in the drawing. In flight the engine produces a thrust T of 62 300 N that is parallel to the ground. The rotational axis in the drawing is perpendicular to the plane of the paper. With respect to this axis, find the magnitude of the torque due to (a) the weight and (b) the thrust. Axis 2.50 m 32.0° Problem 5

A uniform ladder 5.0 m long rests against a frictionless, vertical wall with its lower end 3.0 m from the wall. The ladder weighs 140 N. A man weighing 620 N climbs slowly up the ladder. Start by drawing a free-body diagram of the ladder. What is the actual frictional force when the man has climbed 1.0 m along the ladder? [Hint: Draw a free body diagram to determine what forces are at play. Then use the torque formula (T = Fxrx sine) to find the net torque.]
To a light beam (of negligible mass), two antiparallel forces are applied, as shown in the figure. These forces cause a net torque equal to 8.9 Nm (and with the same direction as that caused by F2) at the left end of the beam. If F1 = 9.8 N and F2 = 5.7 N, determine the distance "l" that separates them.
