Two masses, Ma(4kg) and Mb(6kg), are connected by a massless string and move on a horizontal surface. A horizontal pulling force, F, is applied to Mb. The coefficient of kinetic friction is uk=0.25 between Ma and the surface, but uk=0 between Mb and the surface.
Draw and label the physical situation.
Draw and label the appropritate free-bodu diagrams.
If the acceleration of the mass is 2.5 m/s2, determine the tension in the spring.
Determine the net force acting on Mb.
Determine the value of the pulling force, F.
An object is placed in front of a converging lens in such a position that the lens (f = 11.6 cm) produces a real image located 22.9 cm from the lens.
