A 16.2 kg box (labelled m1) rests on a table. Weight of box is 160N, and the normal force acting on it from the table is 160N. A second box m2, of mass 1.93 kg, is placed on top of the 16.2 kg box. 1. Determine the normal force (in newtons) that the table now exerts on the 16.2 kg box. 2. Determine the normal force (in newtons) that the 16.2 kg box exerts on the 1.93 kg box.
Two masses, m1 and m2 are connected by a frictionless pulley and a massless string (idealpulley system). One mass, m1 sits on a 25o incline that is also frictionless, the other mass issuspended in air, as shown in figure 2. The mass on the incline (m1) has a mass of 5kg. Bothmasses are at rest.a) Draw a free-body diagram for both masses.b) What is the value of m2?
