23)According to the figure, we have two block of mass m, = 1 kg , and my = 1.5 kg that are connected to each other through a pulley with negligible friction with the radius of R = 10 cm. The system is released from rest and block 2 falls 1 meter in 2 seconds without the cord slipping on the pulley. 1. What is the magnitude of the acceleration of the blocks? 2. What are the tension 71, and T2? 3. What is the magnitude of the pulley's angular acceleration? 4. What is the net torque on the pulley? 5. What is the rotation inertia of the pulley? R T1 To 24)According to the figure, a 1g bullet is fired with a speed of 1.8 x 105 m/s into a 0.5 kg block attached to the end of a 0.6 m nonuniform rod of mass 0.5 kg. The block-rod-bullet system then rotates in the plane of the figure, about a fixed axis at A. The rotational inertia of the rod alone about that axis at A is 0.06 kg. m2. Treat the block as a particle.. 1. What then is the rotational inertia of the block-rod-bullet system about point A?2. What is the initial angular momentum of the bullet? 3. What is the angular speed of the system about A just after the impact? 4. What is the final rotational kinetic energy of the system? A Rod Block Bullet 25)A uniform beam is 5.0 m long and has a mass of 53 kg. the beam is supported in a horizontal position by a hinge and a cable, with angle 0 = 60. 1. Draw a free body diagram for the system. 2. Write down the condition of equilibrium on the forces. 3. Write down the condition of equilibrium on the torques. 4. What is the horizontal component of the force on the beam from the hinge? 5. What is the vertical component of the force on the beam from the hinge?\f26) A train is travelling from station A to station C. However, these stations are not directly connected, so the train must go to station B before going to C. Station C is located 18km north and 10km east of station A. Station B is at a distance of 8.5 km from station A, in a direction 45 north of west. Assume the tracks between stations are perfectly straight. A) Draw a rough sketch of the train's route. b) Express the displacement from A to B in terms of its x and y components. c) Find the displacement from B to C in terms of its x and y components. d) What is the distance from B to C? e) How much larger is the total distance of the train's path compared to the distance directly from A to C? Take east to be the x direction and north to be the y direction. Express all answers in kilometers, to one decimal point. 27) A tennis player hits a ball at 45 degrees above horizontal with a speed of 20 m/s. The court has a total length of 20 m and the ball is hit at a distance of 8 m from the net. If the height of the net is 1 m, answer the following questions: a) What are the vertical and horizontal components of the initial velocity of the ball? b) How long does it take for the ball to reach the net? c) Does the ball clear the net? d) Other parameters remaining same, what is the maximum initial speed of the ball such that it still lands inside the court
