Figure 5 shows a Crate A and a Block B connected by a cable and pulley system at rest. The mass of Crate A is mA = 25 kg. The coefficient of static friction between the Crate A and the surface is 0.4. The angle theta is 60 degrees. It is also know that the tension in the cable is 115.9 N. in the question that folows, select the answer that is obsest o the true vatue What is the normal force (N) pushing up on Crate A by the surtace in units of N? 1449 115.9 173.9 86.9
