g and 30 cm each, respectively. Both M1 and M2 rest on frictionless surfaces and the system starts from rest. (a) Draw the fbd for each of M1, M2 and the pulley. (b) Write the equations of motion for each of M1, M2 and the pulley. (c) Calculate the linear acceleration of the two masses, as well as the angular acceleration of the pulley. (d) Calculate the angular velocity of the pulley after M1 and M2 have been displaced linearly by 2 m. Q2) (10 points) A basketball is thrown with an initial speed v0 of 10.8 m/s at 400 above horizontal, and it enters the hoop from above. The ball is released at 2.00 m above the ground. The hoop is 3.05 m above the ground and 10.0 m away from the player. (a) Find the time at which the ball passes through the hoop. (b) Find the ball’s velocity (express in component form) just when it enters the hoop. (c) Find the ball’s maximum height. Q3) (5 Points) An object is thrown up from the top of a building of height of 400 m with an initial velocity of 20 m/s. (a) Find the position and the velocity of the object 5 s later. (b) With what velocity will it hit the ground? (c) At the same time the first object is thrown up, a second object is thrown up from the ground at 100 m/s. Will the two objects collide? If yes, calculate when and where,

. If there is an​ intruder, system A sounds an alarm with probability 0.85 and system B sounds an alarm with probability 0.95. If there is no​ intruder, system A sounds an alarm with probability 0.20 and system B sounds an alarm with probability 0.15 . ​Now, assume that the probability of an intruder is 0.4 . If both systems sound an​ alarm, what is the probability that there is an​ intruder?

litarianism. To begin with, provide a full description of left-wing authoritarianism. Then identify two traits of totalitarian syndrome and explain why you believe they support the assertion that left-wing authoritarianism is more similar to totalitarianism. There are different understandings as to the nature of representation in an indirect democracy. Name and describe each type. Finally, explain which of these you could expect to find in the parliamentary system and why. What, in the parliamentary context, is confidence? Why is it important, how might it be lost, and what happens if it is lost? The Canadian and the US political systems each contain a Senate. In one of the regimes the Senate is the dominant chamber, in the other it is not. Identify which is which and explain why. Provide a full description of the characteristics of a federal state. In your view, how would Plato and Aristotle classify this type of governmental system?

ction between the floor and book is µk. Using the information given in the figure: (a) draw free body diagrams for both the books, and also for the combined system (of mass m1+m2), (b) find acceleration of the books along horizontal direction, and (c) find the magnitude and direction of the force exerted by the left book on the right book. 3.A car of mass 1500-kg enters a circular path at point P and leaves at point Q (see the figure) at constant speed of 5.0m/s, and the frictional force acting on its tires is 2500-N. a) how long it takes to reach point Q from point P, and b) what should be the minimum value of the coefficient of static friction between the tires and the road? 4)In an elevator which is accelerating downward at 2.5ms−2 , a 25-kg block hangs from a spring attached to the ceiling of the elevator. If spring gets stretched by 0.15m, find its spring constant.
