Question

A pulley with mass Mp and a radius Rp, is attached to the ceiling and rotates with no friction about its pivot. Mass M2 is larger than mass m1. The quantities Tn and g are the magnitudes of the various tensions and the gravitational acceleration. NOTATION: C.M. = center of mass. Select T-True, F-False, G-Greater than, L-Less than, E-Equal to. If the first is T, the second L and the rest E, enter TLEEEE) A)T3is . . m1g+M2g+Mpg. B)T1?. T2 C)T1+T2is?. T3 D)m1g is ?. T1. E) The C.M. of Mp+M1+M2 accelerates. F) The acceleration ofM2 is ?.. that of m1. Answer: A 28.5-kg block(m1) is on a horizontal surface, connected to a 6.1-kg block (m2) by a massless string as shown in the Figure below. The frictionless pulley has a radius R = 5.3 cm and a moment of inertia I = 0.09 kg*m^2. A force F = 219.3 N acts on m1 at an angle theta = 30.3 degree. There is no friction between m1 and the surface. What is the upward acceleration of m2?

Explanation / Answer

12. The horizontal component of the applied force is 219.3 *cos30.3 =189.34 N= F say.

I = mr
