Physics-Homework 2 . Unless otherwise specified, each answer should be a number with two decimal digits and the corresponding units. • Submit the complete solution of each exercise by Thursday, April 28th to the TA student. Notice: • 2 points for each correct numerical value or "yes/no" answer. 0.5 points for each correct unit. Total points for homework 2: 15. Exercise 1 (points: 5) A car of mass m 1200 kg makes a turn around a curve, on a level road, of radius r = 300 m. If the maximum value of the friction force is farax=1300 A, what is the maximal speed (arax) the car can reach without sliding? Express MAX both in (A) and (B). Exercise 2 (points: 2.5 In the system in Figure 1 the pulley rotates around its axle without any friction. The pulley shall be considered as a homogeneous cylinder of mass = 4kg and radius r (hence, I = m²). The mass of the rope can be neglected. Moreover, the rope does not slip on the pulley. The mass of the two hanging objects are: m = 4 kg and = 2 kg. What is the magnitude of the acceleration of the two objects?
