Question

2. [1pt] Answer True, False, or Cannot tell to each of the four statements below. E.g., if the answer to the first statement is 'true' and to the rest, cannot tell', enter TCCC. a. A wheel turns on a frictionless axle. A string wrapped around the rim of the wheel is connected to a mass. The mass is released at =0 and hits the floor at t=1. The graph shows a possible o - t behaviour for this situation. b. A square plate can rotate about an axle through its centre. One of three forces of equal magnitude can be applied to the plate, as shown. The angular acceleration of the plate is the same whichever of the forces is applied. c. If force F, was reversed, the object would not rotate about the axle. (Note: F, = F, <F) axle d. The solid cylinders and the cylindrical shells have the same mass, the same radius, and turn on frictionless axles. A rope is wrapped around each of them and is acted on as shown. Cylinder 1 has a larger angular acceleration than cylinder shell 4. 1 solid solid 1 100 100 100 10N Answer: Submit All Answers
